SAFETY AND GENERAL INFORMATION
Information and Instructions on RF Energy Exposure and Product SafetyREAD THIS IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION BEFOREUSING YOUR MOTOROLA HANDHELD PORTABLE TWO-WAY RADIO
The information provided in this document supersedes the general safety information contained in user guidespublished prior to June 2001. For information regarding radio use in a hazardous atmosphere please refer to theFactory Mutual (FM) Approval Product Listing Manual or Instruction Card, which is included with radio modelsthat offer this capability.
Compliance with RF Energy Exposure StandardsYour Motorola two-way radio is designed and tested to comply with a number of national and internationalstandards and guidelines (listed below) regarding human exposure to radio frequency electromagnetic energy.This radio complies with the IEEE (FCC) and ICNIRP exposure limits for occupational/controlled RF exposureenvironment at duty cycles of up to 50% talk-50% listen and should be used for occupational use only. In terms ofmeasuring RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable RFenergy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode. Notethat the approved, supplied batteries for this radio are rated for a 5-5-90 duty cycle (5% talk - 5% listen - 90%standby), even though this radio complies with the FCC occupational exposure limits at duty cycles of up to 50%talk.
Your Motorola two-way radio complies with the following RF energy exposure standards and guidelines:
• United States Federal Communications Commission, Code of Federal Regulations; 47CFR part2 sub-part J
• American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers(IEEE) C95. 1-1992
• Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition• International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998• Ministry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radio frequency Elec-
tromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999• Australian Communications Authority Radiocommunications (Electromagnetic Radiation -
Human Exposure) Standard 2001• ANATEL, Brazil Regulatory Authority, Resolution 256 (April 11, 2001) “additional requirements
for SMR, cellular and PCS product certification.”
Operational Instructions and Training GuidelinesTo ensure optimal performance and compliance with the occupational/controlled environment RF energyexposure limits in the above standards and guidelines, users should transmit no more than 50% of the time andalways adhere to the following procedures:
Transmit and ReceiveTo transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the PTT button.
Hand-held Radio OperationHold the radio in a vertical position with the microphone one to twoinches (2.5 to 5 cm) away from the lips.
Body-worn OperationAlways place the radio in a Motorola approved clip, holder, holster, case,or body harness for this product. Use of non-Motorola-approvedaccessories may exceed FCC RF exposure guidelines.
If you do not use a Motorola approved body-worn accessory and are notusing the radio in the intended use position in front of the face, then ensure the antenna and the radio are kept2.5 cm (one inch) from the body when transmitting.
2.5 to 5.0 cm(1 to 2 in.)
ii
Antennas & BatteriesUse only Motorola approved supplied antenna or Motorola approved replacement antenna.Unauthorized antennas, modifications, or attachments could damage the radio and may violate FCC regulations.
Use only Motorola approved supplied batteries or Motorola approved replacement batteries.Use of non-Motorola-approved antennas or batteries may exceed FCC RF exposure guidelines.
Approved AccessoriesFor a list of approved Motorola accessories please contact your dealer, or local Motorola representative.
ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY
FacilitiesTo avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility whereposted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive toexternal RF energy.
AircraftWhen instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be in accordancewith applicable regulations per airline crew instructions.
Medical Devices
• Pacemakers
The Advanced Medical Technology Association (AdvaMed) recommends that a minimum separation of 6 inches(15 centimeters) be maintained between a handheld wireless radio and a pacemaker. These recommendationsare consistent with those of the U.S. Food and Drug Administration.
Persons with pacemakers should:
• ALWAYS keep the radio more than 6 inches (15 centimeters) from their pacemaker when theradio is turned ON.
• not carry the radio in the breast pocket.• use the ear opposite the pacemaker to minimize the potential for interference.• turn the radio OFF immediately if you have any reason to suspect that interference is taking
place.
• Hearing Aids
Some digital wireless radios may interfere with some hearing aids. In the event of such interference, you maywant to consult your hearing aid manufacturer to discuss alternatives.
• Other Medical Devices
If you use any other personal medical device, consult the manufacturer of your device to determine if it isadequately shielded from RF energy. Your physician may be able to assist you in obtaining this information.
Driver SafetyCheck the laws and regulations on the use of radios in the area where you drive. Always obey them.
When using your radio while driving, please:
• Give full attention to driving and to the road.• Use hands-free operation, if available.• Pull off the road and park before making or answering a call if driving conditions so require.
NOTE Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed, or otherwise configured for electromagnetic compatibility.
iii
OPERATIONAL WARNINGS
For Vehicles With an Air BagDo not place a portable radio in the area over an air bag or in the air bag deployment area. Airbags inflate with great force. If a portable radio is placed in the air bag deployment area and theair bag inflates, the radio may be propelled with great force and cause serious injury tooccupants of the vehicle.
Potentially Explosive AtmospheresTurn off your radio prior to entering any area with a potentially explosive atmosphere, unless it is a radio typeespecially qualified for use in such areas as “Intrinsically Safe” (for example, Factory Mutual, CSA, UL, orCENELEC). Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosiveatmosphere can cause an explosion or fire resulting in bodily injury or even death.
Blasting Caps and AreasTo avoid possible interference with blasting operations, turn off your radio when you are near electrical blastingcaps, in a blasting area, or in areas posted: “Turn off two-way radio.” Obey all signs and instructions.
OPERATIONAL CAUTIONS
AntennasDo not use any portable radio that has a damaged antenna. If a damaged antenna comes intocontact with your skin, a minor burn can result.
BatteriesAll batteries can cause property damage and/or bodily injury such as burns if a conductive material such asjewelry, keys, or beaded chains touch exposed terminals. The conductive material may complete an electricalcircuit (short circuit) and become quite hot. Exercise care in handling any charged battery, particularly whenplacing it inside a pocket, purse, or other container with metal objects.
NOTE The areas with potentially explosive atmospheres referred to above include fueling areassuch as below decks on boats, fuel or chemical transfer or storage facilities, and areaswhere the air contains chemicals or particles, such as grain, dust or metal powders. Areaswith potentially explosive atmospheres are often but not always posted.

POWER UP SELF-TEST
1.0 Error CodesTurning on the radio using the on/off volume control starts a self-test routine which checks the RAM,ROM checksum, EEPROM hardware and EEPROM checksum. If these checks are successfullycompleted, the radio will generate the Self-Test Pass Tone. If the self-test is not successful, a “bonk”is heard. Radios with displays are able to display these error messages:
• “RAM TST ERROR” for <RAM Test Error>• “ROM CS ERROR” for <ROM Checksum Error>• “EEPRM HW ERROR” for <EEPROM Hardware Test Error>• “EEPRM CS ERROR” for <EEPROM Checksum Error>
NOTE Radio without display emits only “bonk” (300 Hz) tone if it fails the self-test.
Error Code Explanation Corrective Action
“RAM TST ERROR” RAM Test Failure Retest radio by turning it off and turning it on again. Ifmessage reoccurs, replace RAM (U405).
“ROM CS ERROR” ROM Checksum iswrong.
Reprogram FLASH Memory, then retest. If messagereoccurs, replace ROM (U406).
“EEPRM HW ERROR” Codeplug structuremismatch, nonexistence ofcodeplug.
Reprogram codeplug with correct version and retestradio. If message reoccurs, replace EEPROM(U407).
“EEPRM CS ERROR” Codeplug check-sum is wrong.
Reprogram codeplug.
No Display Display module isnot connectedproperly.Display module isdamaged.
Check connection between main board and displaymodule.
Replace with new display module.

CONTROLLER INFORMATION
1.0 OverviewThis section provides a detailed theory of operation for the radio and its components.
2.0 Radio Power Distribution
Figure 4-1 illustrates the DC distribution throughout the radio board. A 7.5V battery (BATT 7.5V)supplies power directly to the electronic on/off control as UNSWB+. When the radio is turned on,MECH_SWB+ (on/off/volume control) will trigger the electronic on/off control(momentary-on path),then SWB+ is distributed as shown in Figure 4-1. Vdda from 3.3V Vdda regulator will then supply themicroprocessor. Data is then sent to ASFIC_CMP to turn on GCB4(DAC). GCB4 will take over themomentary-on path within 12ms. SWB+ will continue to support the whole board until the radio isturned off.
Radio will be turned-off on two conditions;
1. MECH_SWB+ turned off
2. Low battery

4-2 Controller Board
When low battery level is detected by the microprocessor through both conditions above, it will storethe radio personality data to EEPROM before turning off.
3.0 Controller Board3.1 General
The controller board is the central interface between the various subsytems of the radio. It isseparated into digital and audio architectures. The digital portion consists of a special Motorolamicrocontroller (HC11FL0). The audio power amplifier (Audio PA) and audio/signalling/filter/companding IC (ASFIC_CMP) form the backbone of the audio/signalling architecture.

3.2 Digital ArchitectureMCU configurationThere is one common MCU architecture for low-tier as well as for the high-tier products. It covers theConventional and Trunking portables. An open architecture system with the new HC11FL0 as theprocessor is used. Combinations of different size RAM, ROM and EEPROM are available for variousapplication software.
REAL TIME CLOCK (RTC)This radio supports Real Time Clock (RTC) module for purposes of Message Time Stamping andTime Keeping. The RTC module resides in the micro-processor HC11FL0. It is kept alive by a back-up Lithium Ion battery when the primary battery is removed.
Circuit DescriptionThe RTC module which resides in the HC11FL0 is powered by the ModB/Vstby pin and PI6/PI7 formthe crystal oscillator circuit. Clock frequency of 38.4kHz from a crystal oscillator provides thereference signal. In the processor, the frequency is divided down to 1Hz.
As the RTC module is powered separately from the processor Vdd, the RTC is kept alive through theModB / Vstby pin when the radio is switched off. A small button Lithium Ion battery continues to feedthe RTC when the primary battery is removed.
A MOSFET Q416 switches in the LiO supply when Vdd is removed. Q416 also provides isolation fromBOOT_CTRL function in the event of radio program flashing. A small 3.3V regulator is used to chargethe LiO battery.

Section 5
KEYPAD BOARD INFORMATION
1.0 Theory of OperationKeypadThe LED_EN setting is set by the codeplug. When the value is set to high, the LED will not light upduring power up and vice versa.
U602 is a comparator that will compare the voltage when any one of the keypad row or keypadcolumn keys is being pressed. Therefore when a key is being pressed, it will send a message to themicroprocessor through the output (KEY_INT) telling it that a key has been pressed. Themicroprocessor will then sample the Analog to Digital voltages at the keypad row and keypad columnand map it with the table so that the key being pressed can be identified. Once the key has beenidentified, the message that corresponds to the key will show up at the display.

3.0 Transmitter
3.1 General(Refer to Figure 6-1)
The UHF transmitter contains five basic circuits:
1. power amplifier
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U101) and
2. PRF1507 LDMOS PA (Q110).
The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V.
This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an inputsignal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in thefrequency range of 403-470MHz.
The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of0.3W. The current drain would typically be 1300mA while operating in the frequency range of 403-470MHz. The power output can be varied by changing the biasing voltage.

3.1.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102)pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias thediodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, whichoperates as a quarter wave transmission line, transforms the low impedance of the shunt diode to ahigh impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, andhence, there exists a low attenuation path between the antenna and receiver ports.
3.1.3 Harmonic Filter
The harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filterfor UHF is that of a modified Zolotarev design. It has been optimized for efficiency of the powermodule. This type of filter has the advantage that it can give a greater attenuation in the stop-band fora given ripple level. The harmonic filter insertion loss is typically less than 1.2dB.
3.1.4 Antenna Matching Network
A matching network which is made up of L116 is used to match the antenna's impedance to theharmonic filter. This will optimize the performance of the transmitter and receiver into an antenna.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio.The current to the final stage of the power module is supplied through R101, which provides a voltageproportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC)within the PCIC to regulate the output power of the transmitter.
The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of thecontrol loop. The reference voltage level is programmable through the SPI line of the PCIC.
There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135)in controlling the transmitter rising and falling time. These are necessary in reducing the powersplatter into adjacent channels.
CR105 and its associated components are part of the temperature cut back circuitry. It senses theprinted circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC.If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will bereduced so as to reduce the transmitter temperature.

4.0 Receiver
4.1 Receiver Front-End(Refer to UHF Receiver Front End Schematic Diagram on page 6A-18 and UHF TransmitterSchematic Diagram on page 6A-22)
The RF signal is received by the antenna and applied to a low-pass filter. For UHF, the filter consistsof L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. Theantenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104and C107).The signal is then applied to a varactor tuned bandpass filter. The UHF bandpass filtercomprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned byapplying a control voltage to the varactor diodes(CR301 and CR302) in the filter.
The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by themicroprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to thevaractor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filteracross the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After beingamplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpassfilter, consisting of L306, L307, C313, C317, CR304 and CR305.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidthof the filter is about 50 MHz. This enables the filters to be electronically controlled by using a singlecontrol voltage which is DACRx .

The output of the post-RF amplifier filter which is connected to the passive double balanced mixerconsists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. Aftermixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, theRF signal is down-converted to the 45.1 MHz IF signal.
The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor padand a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 andL311. The crystal filter provides the necessary selectivity and intermodulation protection.
4.2 Receiver Back-End(Refer to UHF Receiver Back End Schematic Diagram on page 6A-19)
The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 bycomponents R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5).The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301(pin 3)via C330, C338 and L330 which provides the matching for the IF amplifier and U301.
The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, toproduce the recovered audio at pin 27 of U301. This IF IC is electronically programmable, and theamount of filtering (which is dependent on the radio channel spacing) is controlled by themicroprocessor. Additional filtering, once externally provided by the conventional ceramic filters, isreplaced by internal filters in the IF module (U301).
The IF IC uses a type of direct conversion process, whereby the externally generated second LOfrequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC (U301)synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LOis designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IFIC.
In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close totwice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. Thesecond LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode,CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filterconsisting of C362, C363, C364, R320 and R321.
The IF IC (U301) also performs several other functions. It provides a received signal-strengthindicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor,and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. TheRSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed toU404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audiosignal is also routed to U404 for processing before going to the audio amplifier for amplification.
6A-8 Receiver
4.3 Automatic Gain Control Circuit(Refer to UHF Receiver Front End Schematic Diagram on page 6A-18)
The front end automatic gain control circuit is to provide automatic gain reduction of the front end RFamplifier via feedback. This action is necessary to prevent overloading of backend circuits. This isachieved by drawing some of the output power from the RF amplifier’s output. At high radiofrequencies, capacitor C331 provides the low impedance path to ground for this purpose. CR308 is aPIN diode used for switching the path on or off. A certain amount of forward biasing current is neededto turn the PIN diode on. Transistors Q315 provides this current where upon saturation, current willflow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is anNPN transistor used for switching here. Maximum current flowing through the PIN is mainly limited bythe resistor R319.
Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q315 to saturation henceturning it on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and theinput RF signal power to the radio.
Resistor network at the input to the base of Q315 is scaled to turn on Q315, hence activating theAGC, at certain RSSI levels. In order to turn on Q315, the voltage across the transistor’s base toground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe)present at Q315. The resistor network with thermistor RT300 is capable of providing temperaturecompensation to the AGC circuit, as RSSI generated by U301 is lower at cold temperaturescompared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-Cnetwork used to dampen any transient instability while the AGC is turning on.
Frequency Generation Circuitry 6A-9
5.0 Frequency Generation Circuitry
The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer(U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the twoICs provide many of the functions that normally would require additional circuitry. The synthesizerblock diagram illustrates the interconnect and support circuitry used in the region. Refer to therelevant schematics for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively.The synthesizer in turn generates a superfiltered 4.5V which powers U241.
In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry.Programming for the synthesizer is accomplished through the data , clock and chip select lines fromthe microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessorthat the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized bythe Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runsthrough an internal attenuator for modulation balancing purposes before going out to the VCO.

5.1 Synthesizer(Refer to UHF Synthesizer Schematic Diagram on page 6A-20)
The Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system.The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as referencefrequencies. Together with C206, C207, C208, R204 and CR203 , they build up the referenceoscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF.
The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dcsteering voltage for the VCO and determines the amount of noise and spur passing through .
In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current atpin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked bynormal mode charge pump at pin 43 .
Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier whichis made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3Vsquare waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , putthrough arrays of diodes and capacitors to build up 13.3V at pin 47 of U201.

The VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in boththe receive and the transmit modes of operation. The TRB line (U241 pin 19) determines whichoscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routedfrom U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequencycomparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltageis a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.

6A-12 Frequency Generation Circuitry
The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. Thisdifference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line.
The operation logic is shown in Table 6-1.
In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling thereceive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through amatching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer atT302 (refer to UHF Receiver Front End Schematic Diagram on page 6A-18).
During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. Thisactivates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RFsignal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is theTX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto thecarrier is received through the U201 pin 41.
When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode.In this case, both the receive and transmit oscillators as well as the receive transmit and prescalerbuffer are turned off.

3.0 Transmitter
3.1 General(Refer to Figure 6-1)
The VHF transmitter contains five basic circuits:
1. power amplifier
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U3501) and
2. PRF1507 LDMOS PA (Q3501).
The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V.
This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an inputsignal of 2mW (3dBm) (pin16). The current drain would typically be 130mA while operating in thefrequency range of 136-174MHz.
The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of 0.3W.The current drain would typically be 1800mA while operating in the frequency range of 136-174MHz.The power output can be varied by changing the biasing voltage.

Transmitter 6B-5
3.1.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (D3521 and D3551), a pi network (C3531,L3551 and C3550), and three current limiting resistors (R3571, R3572, R3573 ). In the transmitmode, B+ at PCIC (U3502) pin 23 will go low and turn on Q3561 where a B+ bias is applied to theantenna switch circuit to bias the diodes "on". The shunt diode (D3551) shorts out the receiver port,and the pi network, which operates as a quarter wave transmission line, transforms the lowimpedance of the shunt diode to a high impedance at the input of the harmonic filter. In the receivemode, the diodes are both off, and hence, there exists a low attenuation path between the antennaand receiver ports.
3.1.3 Harmonic Filter
The harmonic filter consists of C3532 to C3536, L3531 and L3532. This network forms a low-passfilter to attenuate harmonic energy of the transmitter to specifications level. The harmonic filterinsertion loss should be less than 1.2dB.
3.1.4 Antenna Matching Network
A matching network which is made up of L3538 and C3537 is used to match the antenna'simpedance to the harmonic filter. This will optimize the performance of the transmitter and receiverinto an antenna.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the Power Control IC (PCIC), U3502 to control the power output of the radio bymaintaining the radio current drain. The current to the final stage of the power module is suppliedthrough R3519 (0.1ohms), which provides a voltage proportional to the current drain. This voltage isthen fedback to the Automatic Level Control (ALC) within the PCIC to keep the whole loop stable.
The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of thecontrol loop. The voltage level is controlled by the microprocessor through the data line of the PCIC.
There are resistors and integrators within the PCIC, and external capacitors (C3562, C3563 andC3565) in controlling the transmitter rising and falling time. These are necessary in reducing thepower splatter into adjacent channels.
U3503 and its associated circuitry acts as a temperature cut back circuitry. This circuitry provides thenecessary voltage to the PCIC to cut the transmitter power when the radio temperature gets too high.
6B-6 Receiver
4.0 Receiver
4.1 Receiver Front-End(Refer toVHF Receiver Front End Schematic Diagram on page 6B-20, VHF Receiver Back EndSchematic Diagram on page 6B-21, and VHF Transmitter Schematic Diagram on page 6B-24)
The RF signal is received by the antenna and applied to a low-pass filter. For VHF, the filter consistsof L3531, L3532, C3532 to C3563. The filtered RF signal is passed through the antenna switch. Theantenna switch circuit consists of two PIN diodes(D3521 and D3551) and a pi network (C3531, L3551and C3550).The signal is then applied to a varactor tuned bandpass filter. The VHF bandpass filtercomprises of L3301, L3303, C3301 to C3304 and D3301. The bandpass filter is tuned by applying acontrol voltage to the varactor diode (D3301) in the filter.
The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by themicroprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to thevaractor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filteracross the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q3302 via C3306. Afterbeing amplified by the RF amplifier, the RF signal is further filtered by a second varactor tunedbandpass filter, consisting of L3305, L3306, C3311 to C3314 and D3302.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidthof the filter is about 12 MHz. This enables the filters to be electronically controlled by using a singlecontrol voltage which is DACRx .

Receiver 6B-7
The output of the post-RF amplifier filter is connected to the passive double balanced mixer whichconsists of T3301, T3302 and CR3301. Matching of the filter to the mixer is provided by C3317,C3318 and L3308. After mixing with the first LO signal from the voltage controlled oscillator (VCO)using high side injection, the RF signal is down-converted to the 45.1 MHz IF signal.
The IF signal coming out of the mixer is transfered to the crystal filter (Y3200) through a resistor pad(R3321 - R3323) and a diplexer (C3320 and L3309). Matching to the input of the crystal filter isprovided by C3200 and L3200. The crystal filter provides the necessary selectivity andintermodulation protection.
4.2 Receiver Back-End(Refer to VHF Receiver Back End Schematic Diagram on page 6B-21)
The output of crystal filter Y3200 is matched to the input of IF amplifier transistor Q3200 by capacitorC3203. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5). The gain controlled IFamplifer provides a maximum gain of about 10dB. The amplified IF signal is then coupled intoU3220(pin 3) via L3202, C3207, and C3230 which provides the matching for the IF amplifier andU3220.
The IF signal applied to pin 3 of U3220 is amplified, down-converted, filtered, and demodulated, toproduce the recovered audio at pin 27 of U3220. This IF IC is electronically programmable, and theamount of filtering (which is dependent on the radio channel spacing) is controlled by themicroprocessor. Additional filtering, once externally provided by the conventional ceramic filters, isreplaced by internal filters in the IF module (U3220).
The IF IC uses a type of direct conversion process, whereby the externally generated second LOfrequency is divided by two in U3220 so that it is very close to the first IF frequency. The IF IC (U3220)synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LOis designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IFIC.
In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close totwice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. Thesecond LO/VCO is a Colpitts oscillator built around transistor Q3270. The VCO has a varactor diode,D3270, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filterconsisting of C3278 to C3280, R3274 and R3275.
The IF IC (U3220) also performs several other functions. It provides a received signal-strengthindicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor,and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. TheRSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U3220 is also used for squelch control. The signal is routed toU404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audiosignal is also routed to U404 for processing before going to the audio amplifier for amplification.
6B-8 Receiver
4.3 Automatic Gain Control Circuit(Refer to VHF Receiver Front End Schematic Diagram on page 6B-20 and VHF Receiver Back EndSchematic Diagram on page 6B-21)
The front end automatic gain control circuit provides automatic reduction of gain, of the front end RFamplifier via feedback. This action is necessary to prevent overloading of backend circuits. This isachieved by drawing some of the output power from the RF amplifier output. At high radiofrequencies, capacitor C3327 provides the low impedance path to ground for this purpose. CR3302 isa PIN diode used for switching the path on or off. A certain amount of forward biasing current isneeded to turn the PIN diode on. Transistor Q3301 provides this current.
Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q3301 to saturation i.e.turned on. RSSI is produced by U3220 and is proportional to the gain of the RF amplifier and the inputpower to the radio.
Resistors R3304 and R3305 are voltage dividers designed to turn on Q3301 at certain RSSI levels. Inorder to turn on Q3301 the voltage across R3305 must be greater or equal to the voltage acrossR3324, plus the base-emitter voltage (Vbe) present at Q3301. Capacitor C3209 is used to dampenany instability while the AGC is turning on. The current flowing into the collector of Q3301, a highcurrent gain NPN transistor, will be drawn through the PIN diode to turn it on. Maximum currentflowing through the PIN is limited by the resistors R3316, R3313, R3306 and R3324. C3326 is afeedback capacitor used to provide some stability to this high gain stage.
An additional gain control circuit is formed by Q3201 and its associated circuitry. Resistors R3206 andR3207 are voltage dividers designed to turn on Q3201 at a significantly higher RSSI level than thelevel required to turn on PIN diode control transistor Q3301. In order to turn on Q3201 the voltageacross R3207 must be greater or equal to the voltage across R3208, plus the base-emitter voltage(Vbe) present at Q3201. As current starts flowing into the collector of Q3201, it reduces the biasvoltage at the base of IF amplifier transistor Q3200 and in turn, the gain of the IF amplifier. The gaincan be controlled in a range of -30dB up to +10dB.
Frequency Generation Circuitry 6B-9
5.0 Frequency Generation Circuitry
The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer(U3701), and the VCO/Buffer IC (U3801). Designed in conjunction to maximize compatibility, the twoICs provide many of the functions that normally would require additional circuitry. The synthesizerblock diagram illustrates the interconnect and support circuitry used in the region. Refer to therelevant schematics for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V which come from U3711 and U3201respectively. The synthesizer in turn generates a superfiltered 4.5V which powers U3801.
In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry.Programming for the synthesizer is accomplished through the data , clock and chip select lines fromthe microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessorthat the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U3701. Internally the audio is digitized bythe Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runsthrough an internal attenuator for modulation balancing purposes before going out to the VCO.

5.1 Synthesizer(Refer toVHF Synthesizer Schematic Diagram on page 6B-22)
The Fractional-N Synthesizer uses a 16.8MHz crystal (Y3761) to provide a reference for the system.The LVFractN IC (U3701) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as referencefrequencies. Together with C3761, C3762, C3763, R3761 and D3761 , they build up the referenceoscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides16.8MHz at pin 19 of U3701 to be used by ASFIC and LVZIF.
The loop filter which consist of C3721, C3722, R3721, R3722 and R3723 provides the necessary dcsteering voltage for the VCO and determines the amount of noise and spur passing through .
In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current atpin 45 of U3701 to put synthesizer within the lock range. The required frequency is then locked bynormal mode charge pump at pin 43 .
Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier whichis made up of C3701 to C3704 and triple diodes D3701, D3702. Two 3.3V square waves ( 180 degout of phase) are first multiplied by four and then shifted, along with regulated 5V, to build up 13.5V atpin 47 of U3701.

The VCOBIC (U3801) in conjunction with the Fractional-N synthesizer (U3701) generates RF in boththe receive and the transmit modes of operation. The TRB line (U3801 pin 19) determines whichoscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routedfrom U3801 pin 12, through a low pass filter, to the prescaler input (U3701 pin 32). After frequencycomparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltageis a DC voltage typically between 3.5V and 9.5V when the PLL is locked on frequency.

The RF section of the VCOBIC(U3801) is operated at 4.54 V (VSF), while the control section of theVCOBIC and Fractional-N synthesizer (U3701) is operated at 3.3V. The operation logic is shown inTable 6-1.
In the receive mode, U3801 pin 19 is low or grounded. This activates the receive VCO by enabling thereceive oscillator and the receive buffer of U3801. The RF signal at U3801 pin 8 is run through amatching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer atT3302.
During the transmit condition, when PTT is depressed, 3.2 volts is applied to U3801 pin 19. Thisactivates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U3801. TheRF signal at U3801 pin 10 is injected into the input of the PA module (U3501 pin16). This RF signal isthe TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto thecarrier is received through U3701 pin 41.
When a high impedance is applied to U3801 pin19, the VCO is operating in BATTERY SAVER mode.In this case, both the receive and transmit oscillators as well as the receive transmit and prescalerbuffer are turned off.

3.1 General(Refer to Figure 6-1)
The UHF transmitter contains five basic circuits:
1. power amplifier
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U101) and
2. PRF1507 LDMOS PA (Q110).
The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V.
This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an inputsignal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in thefrequency range of 450-527MHz.
The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of0.3W. The current drain would typically be 1300mA while operating in the frequency range of 450-527MHz. The power output can be varied by changing the biasing voltage.

3.1.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102)pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias thediodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, whichoperates as a quarter wave transmission line, transforms the low impedance of the shunt diode to ahigh impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, andhence, there exists a low attenuation path between the antenna and receiver ports.
3.1.3 Harmonic Filter
The harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filterfor UHF is that of a modified Zolotarev design. It has been optimized for efficiency of the powermodule. This type of filter has the advantage that it can give a greater attenuation in the stop-band fora given ripple level. The harmonic filter insertion loss is typically less than 1.2dB.
3.1.4 Antenna Matching Network
A matching network which is made up of L116 is used to match the antenna's impedance to theharmonic filter. This will optimize the performance of the transmitter and receiver into an antenna.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio.The current to the final stage of the power module is supplied through R101, which provides a voltageproportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC)within the PCIC to regulate the output power of the transmitter.
The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of thecontrol loop. The reference voltage level is programmable through the SPI line of the PCIC.
There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135)in controlling the transmitter rising and falling time. These are necessary in reducing the powersplatter into adjacent channels.
CR105 and its associated components are part of the temperature cut back circuitry. It senses theprinted circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC.If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will bereduced so as to reduce the transmitter temperature.
Receiver 6C-5
4.0 Receiver
4.1 Receiver Front-End(Refer to UHF Band 2 Receiver Front End Schematic Diagram on page 6C-16 and UHF Band 2Transmitter Schematic Diagram on page 6C-20)
The RF signal is received by the antenna and applied to a low-pass filter. For UHF, the filter consistsof L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. Theantenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104and C107).The signal is then applied to a varactor tuned bandpass filter. The UHF bandpass filtercomprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned byapplying a control voltage to the varactor diodes(CR301 and CR302) in the filter.
The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by themicroprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to thevaractor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filteracross the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After beingamplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpassfilter, consisting of L306, L307, C313, C317, CR304 and CR305.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidthof the filter is about 50 MHz. This enables the filters to be electronically controlled by using a singlecontrol voltage which is DACRx .

The output of the post-RF amplifier filter which is connected to the passive double balanced mixerconsists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. Aftermixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, theRF signal is down-converted to the 45.1 MHz IF signal.
The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor padand a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 andL311. The crystal filter provides the necessary selectivity and intermodulation protection.
4.2 Receiver Back-End(Refer to UHF Band 2 Receiver Back End Schematic Diagram on page 6C-17)
The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 bycomponents R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5).The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301(pin 3)via C330, C338 and L330 which provides the matching for the IF amplifier and U301.
The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, toproduce the recovered audio at pin 27 of U301. This IF IC is electronically programmable, and theamount of filtering (which is dependent on the radio channel spacing) is controlled by themicroprocessor. Additional filtering, once externally provided by the conventional ceramic filters, isreplaced by internal filters in the IF module (U301).
The IF IC uses a type of direct conversion process, whereby the externally generated second LOfrequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC (U301)synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LOis designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IFIC.
In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close totwice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. Thesecond LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode,CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filterconsisting of C362, C363, C364, R320 and R321.
The IF IC (U301) also performs several other functions. It provides a received signal-strengthindicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor,and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. TheRSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed toU404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audiosignal is also routed to U404 for processing before going to the audio amplifier for amplification.
Receiver 6C-7
4.3 Automatic Gain Control Circuit(Refer to UHF Band 2 Receiver Front End Schematic Diagram on page 6C-16)
The front end automatic gain control circuit is to provide automatic gain reduction of the front end RFamplifier via feedback. This action is necessary to prevent overloading of backend circuits. This isachieved by drawing some of the output power from the RF amplifier’s output. At high radiofrequencies, capacitor C331 provides the low impedance path to ground for this purpose. CR308 is aPIN diode used for switching the path on or off. A certain amount of forward biasing current is neededto turn the PIN diode on. Transistors Q315 provides this current where upon saturation, current willflow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is anNPN transistor used for switching here. Maximum current flowing through the PIN is mainly limited bythe resistor R319.
Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q315 to saturation henceturning it on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and theinput RF signal power to the radio.
Resistor network at the input to the base of Q315 is scaled to turn on Q315, hence activating theAGC, at certain RSSI levels. In order to turn on Q315, the voltage across the transistor’s base toground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe)present at Q315. The resistor network with thermistor RT300 is capable of providing temperaturecompensation to the AGC circuit, as RSSI generated by U301 is lower at cold temperaturescompared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-Cnetwork used to dampen any transient instability while the AGC is turning on.
6C-8 Frequency Generation Circuitry
5.0 Frequency Generation Circuitry
The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer(U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the twoICs provide many of the functions that normally would require additional circuitry. The synthesizerblock diagram illustrates the interconnect and support circuitry used in the region. Refer to therelevant schematics for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively.The synthesizer in turn generates a superfiltered 4.5V which powers U241.
In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry.Programming for the synthesizer is accomplished through the data , clock and chip select lines fromthe microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessorthat the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized bythe Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runsthrough an internal attenuator for modulation balancing purposes before going out to the VCO.

5.1 Synthesizer(Refer to UHF Band 2 Synthesizer Schematic Diagram on page 6C-18)
The Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system.The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as referencefrequencies. Together with C206, C207, C208, R204 and CR203 , they build up the referenceoscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF.
The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dcsteering voltage for the VCO and determines the amount of noise and spur passing through .
In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current atpin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked bynormal mode charge pump at pin 43 .
Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier whichis made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3Vsquare waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , putthrough arrays of diodes and capacitors to build up 13.3V at pin 47 of U201.

The VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in boththe receive and the transmit modes of operation. The TRB line (U241 pin 19) determines whichoscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routedfrom U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequencycomparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. Thisvoltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.

The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. Thisdifference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line.
The operation logic is shown in Table 6-1.
In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling thereceive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through amatching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer atT302 (refer to UHF Band 2 Receiver Front End Schematic Diagram on page 6C-16).
During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. Thisactivates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RFsignal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is theTX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto thecarrier is received through the U201 pin 41.
When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode.In this case, both the receive and transmit oscillators as well as the receive transmit and prescalerbuffer are turned off.

3.0 Transmitter
3.1 General(Refer to Figure 6-1)
The VHF transmitter contains five basic circuits:
1. power amplifier
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U101) and
2. PRF1507 LDMOS PA (Q110).
The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V.
This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an inputsignal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in thefrequency range of 330-400MHz.
The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of0.3W. The current drain would typically be 1300mA while operating in the frequency range of 330-400MHz. The power output can be varied by changing the biasing voltage.

6D-4 Transmitter
3.1.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102)pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias thediodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, whichoperates as a quarter wave transmission line, transforms the low impedance of the shunt diode to ahigh impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, andhence, there exists a low attenuation path between the antenna and receiver ports.
3.1.3 Harmonic Filter
The harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filterfor VHF is that of a modified Zolotarev design. It has been optimized for efficiency of the powermodule. This type of filter has the advantage that it can give a greater attenuation in the stop-band fora given ripple level. The harmonic filter insertion loss is typically less than 1.2dB.
3.1.4 Antenna Matching Network
A matching network which is made up of L116 is used to match the antenna's impedance to theharmonic filter. This will optimize the performance of the transmitter and receiver into an antenna.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio.The current to the final stage of the power module is supplied through R101, which provides a voltageproportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC)within the PCIC to regulate the output power of the transmitter.
The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of thecontrol loop. The reference voltage level is programmable through the SPI line of the PCIC.
There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135)in controlling the transmitter rising and falling time. These are necessary in reducing the powersplatter into adjacent channels.
CR105 and its associated components are part of the temperature cut back circuitry. It senses theprinted circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC.If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will bereduced so as to reduce the transmitter temperature.

4.0 Receiver
4.1 Receiver Front-End(Refer to 330-400MHz Receiver Front End Schematic Diagram on page 6D-16 and 330-400MHzTransmitter Schematic Diagram on page 6D-20)
The RF signal is received by the antenna and applied to a low-pass filter. For VHF, the filter consistsof L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. Theantenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104and C107).The signal is then applied to a varactor tuned bandpass filter. The VHF bandpass filtercomprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned byapplying a control voltage to the varactor diodes(CR301 and CR302) in the filter.
The bandpass filter is electronically tuned by the DACRx from U404 which is controlled by themicroprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to thevaractor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filteracross the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After beingamplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpassfilter, consisting of L306, L307, C313, C317, CR304 and CR305.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidthof the filter is about 50 MHz. This enables the filters to be electronically controlled by using a singlecontrol voltage which is DACRx .

6D-6 Receiver
The output of the post-RF amplifier filter which is connected to the passive double balanced mixerconsists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. Aftermixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, theRF signal is down-converted to the 45.1 MHz IF signal.
The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor padand a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 andL311. The crystal filter provides the necessary selectivity and intermodulation protection.
4.2 Receiver Back-End(Refer to 330-400MHz Receiver Back End Schematic Diagram on page 6D-17)
The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 bycomponents R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5).The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301(pin 3)via C330, C338 and L330 which provides the matching for the IF amplifier and U301.
The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, toproduce the recovered audio at pin 27 of U301. This IF IC is electronically programmable, and theamount of filtering (which is dependent on the radio channel spacing) is controlled by themicroprocessor. Additional filtering, once externally provided by the conventional ceramic filters, isreplaced by internal filters in the IF module (U301).
The IF IC uses a type of direct conversion process, whereby the externally generated second LOfrequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC (U301)synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LOis designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IFIC.
In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close totwice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. Thesecond LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode,CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filterconsisting of C362, C363, C364, R320 and R321.
The IF IC (U301) also performs several other functions. It provides a received signal-strengthindicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor,and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. TheRSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed toU404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audiosignal is also routed to U404 for processing before going to the audio amplifier for amplification.
Receiver 6D-7
4.3 Automatic Gain Control Circuit(Refer to 330-400MHz Receiver Front End Schematic Diagram on page 6D-16)
The front end automatic gain control circuit is to provide automatic gain reduction of the front end RFamplifier via feedback. This action is necessary to prevent overloading of backend circuits. This isachieved by drawing some of the output power from the RF amplifier’s output. At high radiofrequencies, capacitor C331 provides the low impedance path to ground for this purpose. CR308 is aPIN diode used for switching the path on or off. A certain amount of forward biasing current is neededto turn the PIN diode on. Transistors Q315 provides this current where upon saturation, current willflow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is anNPN transistor used for switching here. Maximum current flowing through the PIN is mainly limited bythe resistor R319.
Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q315 to saturation henceturning it on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and theinput RF signal power to the radio.
Resistor network at the input to the base of Q315 is scaled to turn on Q315, hence activating theAGC, at certain RSSI levels. In order to turn on Q315, the voltage across the transistor’s base toground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe)present at Q315. The resistor network with thermistor RT300 is capable of providing temperaturecompensation to the AGC circuit, as RSSI generated by U301 is lower at cold temperaturescompared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-Cnetwork used to dampen any transient instability while the AGC is turning on.
6D-8 Frequency Generation Circuitry
5.0 Frequency Generation Circuitry
The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer(U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the twoICs provide many of the functions that normally would require additional circuitry. The synthesizerblock diagram illustrates the interconnect and support circuitry used in the region. Refer to therelevant schematics for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively.The synthesizer in turn generates a superfiltered 4.5V which powers U241.
In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry.Programming for the synthesizer is accomplished through the data , clock and chip select lines fromthe microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessorthat the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized bythe Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runsthrough an internal attenuator for modulation balancing purposes before going out to the VCO.

5.1 Synthesizer(Refer to 330-400MHz Synthesizer Schematic Diagram on page 6D-18)
The Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system.The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as referencefrequencies. Together with C206, C207, C208, R204 and CR203 , they build up the referenceoscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF.
The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dcsteering voltage for the VCO and determines the amount of noise and spur passing through .
In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current atpin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked bynormal mode charge pump at pin 43 .
Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier whichis made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3Vsquare waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , putthrough arrays of diodes and capacitors to build up 13.3V at pin 47 of U201.

Figure 6-5 VCO Block Diagram
The VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in boththe receive and the transmit modes of operation. The TRB line (U241 pin 19) determines whichoscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routedfrom U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequencycomparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. Thisvoltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.

Frequency Generation Circuitry 6D-11
The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. Thisdifference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line.
The operation logic is shown in Table 6-1.
In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling thereceive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through amatching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer atT302 (refer to 330-400MHz Receiver Front End Schematic Diagram on page 6D-16).
During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. Thisactivates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RFsignal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is theTX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto thecarrier is received through the U201 pin 41.
When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode.In this case, both the receive and transmit oscillators as well as the receive transmit and prescalerbuffer are turned off.

6E-4 Transmitter
3.0 Transmitter
3.1 General(Refer to Figure 6-1)
The Lowband transmitter consists of the following basic circuits:
1. power amplifier (PA)
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two LDMOS devices:
1. PA driver, U101 and
2. PA final stage, Q100.
The LDMOS driver (U101) provides 2-stage amplification using a supply voltage of 7.3V. Theamplifier is capable of supplying an output power of 0.3W (pins 6 and 7) with an input signal of 2mWat (pin16). The current drain is typically 120mA while operating in the frequency range of 29.7 - 50MHz. The power output of this stage is varied by the power control loop which controls the voltage onpin 1.
The LDMOS PA is capable of supplying an output power of 8W with an input signal of 0.3W. Thecurrent drain is typically 2000 mA while operating in the frequency range of 29.7 - 50 MHz. The finalstage gate is bias by a voltage from PCIC pin 24. This voltage is the output of a programmable DACinside the PCIC and the output is adjustable with the radio tuner.

Transmitter 6E-5
3.1.2 Antenna Switch
The antenna switch circuit consists of two pin diodes (D100 and D101), a RF network (C147 andL103), and a DC feed network (L104, C144 and current limiting resistor R101). In the transmit mode,PCIC (U102) pin 32 goes high supplying current via the feed network to bias the diodes “on”. Theshunt diode (D101) shorts out the receiver port and L103 is connected from the RF path to ground.L103 and the input capacitance of the lowpass filter form a parallel resonant circuit, effectivelydisconnecting the receiver port from the antenna while not loading the transmit path. In the receivemode, pin 32 goes low and the.the diodes are off. D100 looks like a high impedance disconnectingthe transmitter from the antenna while L103 and C147 form a series resonant circuit to connect thereceiver to the antenna.
3.1.3 Harmonic Filter
The harmonic filter consists of components C103, C106, C107,C110, C111, C114, C115 and 3inductors which are a part of the SH100 assembly. The harmonic filter for lowband is pole zero designwhich give greater attenuation lower in frequency where the harmonic energy of the transmitter is thegreatest and less attenuation high in frequency where there is less harmonic energy. The harmonicfilter insertion loss is typically less than 0.8 dB
3.1.4 Antenna Matching Network
The antenna matching network (T100) matches the antenna's impedance with the harmonic filter tooptimize the performance of the transmitter and receiver.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the PCIC (U102) to regulate the power output of the radio. To accomplish this,the voltage across R102 is sensed. This voltage drop is directly proportional to the current drawn inthe final stage of the transmitter. This voltage is compared to a programmable reference inside thePCIC and the voltage on PCIC pin 4 adjusted. Pin 4 connects to the PA driver IC (U101) pin 1 viaresistor R100 and varies RF output power of the driver. This controls the current drain of the finalstage and sets the output power.
3.1.6 Temperature Cut Back Circuit
Temperature sensor VR101 and associated components are part of a temperature cut back circuit.This circuit senses the printed circuit board temperature around the transmitter circuits and outputs aDC voltage to the PCIC. If the DC voltage produced exceeds the set threshold of the PCIC, thetransmitter output power decreases to reduce the transmitter temperature.
6E-6 Receiver
4.0 Receiver
4.1 Receiver Front-EndThe RF signal received by the antenna is routed through the transmitter lowpass filter and antennaswitch. These circuits are described in the transmitter section.The signal next passes through ahighpass filter consisting of L501, L502, C538, C533 and C504. This filter serves to reject below bandsignals and has a 3 dB corner frequency of 27 MHz.
The output of the highpass filter is connected to an RF amp consisting of Q509 and associatedbiasing components. This is a BJT amplifier powered off 5 volts and has 13 dB of gain. The amplifierdrives a lowpass filter consisting of L503, L504 L507, C534, C535, C536, C537 and C515. This filteris a pole zero design that filters off harmonic components from the RF amp. The 3 dB corner of thisfilter is at 56 MHz.
The output of the lowpass filter is connected to the passive double balanced mixer consisting ofcomponents T501, T502, and D501. After mixing with the first local oscillator up-converted to a109.65 MHz IF signal.
The IF signal coming out of the mixer is transferred to the crystal filter (FL301) through a resistor pad(R507, R508 and R509) and a diplexer (C516 and L508). Matching to the input of the crystal filter isprovided by L301, L302, C301 and C302. The 3 pole crystal filter provides the necessary selectivityand intermodulation protection.

Receiver 6E-7
4.2 Receiver Back-EndThe output of crystal filter FL301 is connected to the input of IF amplifier transistor U301. ComponentsL303 and C348 and R301 form the termination for the crystal filter and the signal is coupled to onegate of U301 by C303. The IF amplifier is a dual gate MOSFET powered off of the 5 volt supply. Thefirst gate receives the IF signal as indicated previously. The second gate receives a DC voltage fromU302 which serves as an AGC control signal. This signal reduces the gain of the IF amplifier toprevent overload of the IF IC, U303. The gain can be varied from a maximum of 13 dB to anattenuation of 55 dB. The output IF signal from U301 is coupled into U303 (pin 3) via C306, R304 andL304 which provides matching for the IF amplifier and U303.
The IF signal applied to pin 3 of U303 is amplified, down-converted, filtered, and demodulated, toproduce recovered audio at pin 27 of U303. This IF IC is electronically programmable, and theamount of filtering, which is dependent on the radio channel spacing, is controlled by themicroprocessor. Additional filtering, once externally provided by the conventional ceramic filters, isreplaced by internal filters in IF IC U303.
The IF IC uses a type of direct conversion process, whereby the externally generated second LOfrequency is divided by two in U303 so that it is very close to the first IF frequency. The IF IC (U303)synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO isdesigned to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC.
In the absence of an IF signal, the VCO searches for a frequency, or its frequency will vary close totwice the IF frequency. When an IF signal is received, the VCO locks onto the IF signal. The secondLO/VCO is a Colpitts oscillator built around transistor Q301. The VCO has a varactor diode, CR301,to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consistingof components C308, C309, and R310.
The IF IC (U303) also performs several other functions. It provides a received signal-strengthindicator (RSSI) and a squelch output. The RSSI voltage is also used to control the automatic gaincontrol (AGC) circuit at the back end.
The demodulated signal on pin 27 of U303 is also used for squelch control. The signal is routed toU404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audiosignal is also routed to U404 for processing before going to the audio amplifier for amplification.
4.3 Automatic Gain Control CircuitThe automatic gain control circuit provides automatic reduction of gain to prevent overloading ofbackend circuits. This is achieved by lowering the voltage on one gate of U301 which will reduce thedrain current in that part and lower its gain.
The Radio Signal Strength Indicator (RSS I) voltage signal for the IF IC (U303) is used to drive theAGC processing circuitry consisting of R306, R307, R308, R309 C307 and U302. As the receivedsignal gets stronger, the RSSI line will rise. When the RSSI line passes a certain threshold, thevoltage at the output of U302 will begin to drop. This voltage is connected to one gate of IF amplifierU301 through resistor R305. As this voltage decreases, it will lower the drain current in U301 andreduce the gain of the stage. This will limit the power incident on the IF IC, U303.
6E-8 Frequency Generation Circuitry
5.0 Frequency Generation Circuitry
The frequency generation circuit, shown in Figure 6-3 , is composed of Low Voltage Fractional-Nsynthesizer U205 and discrete RX VCO, TX VCO.and buffers as well other supporting circuitry. Thesynthesizer block diagram illustrates the interconnect and support circuitry used in the region. Referto the schematic for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V. The 5 volt signal to the synthesizer as well asthe rest of the radio is provided by U204. The 3.3 v signal is provided from U400 in the controller. The5V signal goes to pins 13 and 30 while the 3.3V signal goes to pins 5, 20, 34 and 36 of U201. Thesynthesizer in turn generates a superfiltered 4.3V which powers the VCOs and buffers.
In addition to the VCO, the synthesizer also interfaces with the logic and ASFIC circuitry.Programming for the synthesizer is accomplished through the data, clock and chip select lines (pins7, 8 and 9) from the microprocessor, U409. A 3.3V dc signal from pin 4 indicates to themicroprocessor that the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U205. Internally the audio is digitized bythe Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runsthrough an internal attenuator for modulation balancing purposes before going out at pin 41 to theVCO.

5.1 SynthesizerThe Fractional-N synthesizer, shown in Figure 6-4, uses a 17.0 MHz crystal (Y201) to provide areference for the system. Along with being used in the LVFracN, the 17.0 MHz signal is provided atpin 19 of U205 for use by the ASFIC and LVZIF.
The LVFractN IC (U205) further divides this by 8 internally to give 2.125 MHz to be used as thereference frequency in the frequency synthesis. While UHF and VHF can use other references,(divide by 7 or divide by 7/8), only the divide by 8 function is valid for lowband.
The internal oscillator device in the LVFracN together with C236, C237, C242, R219, CR211and Y201comprise the reference oscillator. This oscillator is temperature compensated is capable of 2.5 ppmstability over temperatures of -30 to 85°C. There is temperature compensation information that isunique to each crystal contained on Y201 that is programmed into the radio when built.
The loop filter consists of components C256, C257, C259, R224, R225 and R228. This circuitprovides the necessary dc steering voltage for the VCO and determines the amount of noise and spurpassing through.
To achieve fast locking for the synthesizer, an internal adapt charge pump provides higher current atpin 45 of U205 to put the synthesizer within lock range. The required frequency is then locked bynormal mode charge pump at pin 43.
Both the normal and adapt charge pumps get their supply from the inductive voltage multiplier madeup of C240, C246, C247, C249, D201, and L223. This circuit provides 13.3V at pin 47 of U205.

5.2 VCO - Voltage Controlled Oscillator
5.2.1 Receive VCO
The receive VCO is a Colpitts type design and using two active devices in parallel, Q202 and Q204.The oscillator is powered off of the 4.3 volt super filter supply when the AUX3 line goes low. Theoscillator operates from 139 to 160 MHz, and the frequency is tuned by varactor diodes CR201 andCR202.
5.2.2 Transmit VCO
The transmit VCO is a Hartley type design with active devices Q203. The oscillator is powered off ofthe 4.3 volt super filter supply when the AUX2 line goes low. The oscillator operates from 29.7 to 42MHz for Range 1 and 35 to 50 MHz for Range 2. The frequency is tuned by varactor diodes in U203.Note that the values of the inductive tap, L208 and L209, and the capacitor C215 which couples thevaractor to the oscillator tank vary between the ranges.
5.2.3 Buffer
Both the receive and transmit VCO are fed to a buffer amplifier Q201. This is a BJT amplifier thatboosts the signal levels to +4 dBm and provides reverse isolation to the oscillators. The amplifier ispowered off the 4.3 volt super filter supply and the feed network is combined with the transmit filter.
5.2.4 Diplexer and Output Filters
The output of the buffer drives a pair of parallel filters. One filter is a lowpass filter in the TX pass thatpasses 29.7 - 50 MHz signals for the transmitter into the power amplifier while rejecting the receiveLO injection signals at 139 - 160 MHz. This filter is comprised of L204, L211, L212, C230 and C231.
The other filter is a highpass filter which passes 139 - 160 MHz signals for the receive LO into themixer while rejecting the transmit injection signals at 29.7 -50 MHz. This filter is comprised ofC228,C229,C235 and L215.
5.2.5 Prescalar Feedback
The prescalar input signal for receive and transmit is tapped off of the outputs of each filter byresistors R234 and R238. This signal is routed to U205 pin 32. After frequency comparison in thesynthesizer, current is transferred in the loop filter and a control voltage is generated at the output ofthe loop filter to adjust the frequency of the VCO. This voltage is a DC voltage between 3.5V and 9.5Vwhen the PLL is locked on frequency.
