The CCI 3-Sector, 24 Base Radio, RF Distribution System provides the most efficient andflexible means of deploying a three sector site with 24 Base Radio capacity. The 24 Base Ra-dio RF distribution System was specifically optimized to work in conjunction with the Motorola

4 Base Radio primary Rack with self contained iSC and iMU. This configuration results in acomplete 3-Sector, 24 Base Radio system using only four Racks: One Motorola 4-BR PrimaryRack, two CCI 6-BR Primary Racks and one CCI 8-BR Multi-sector Expansion Rack. The Mo-torola Primary Rack contains the iMU and dual iSC, a three branch Receiver Multi-coupler, Dual

3:1 Hybrid Combiners and room for four Base Radios. The CCI Duplexed RFDS PrimaryRacks contain a three branch Receiver Multi-Coupler capable of providing 9 outputs per

branch, a Triple Duplexer as-sembly with integrated powermonitoring circuit and threefront panel Power/ VSWRLCD displays, Dual 3:1 Hy-

brid Combiners, a dedicatedExpansion Breaker Paneland all the necessary receive(Rx), transmit (Tx), 5 MHz /1PPS, Ethernet, alarm andpower cabling to install up to6 base radios within the rack.The CCI Multi-sector Expan-sion Rack contains a threebranch Receiver Multi-coupler, three 2:1 Hybrid

Combiners and a dedicatedExpansion Breaker Paneland all the necessary receive(Rx), transmit (Tx), 5 MHz /1PPS, Ethernet, alarm andpower cabling to install up to8 base radios within the rackunit. All Racks are poweredfrom the main -48 VDC bus.

An alarm output is provided

which is compatible with theEnvironmental Alarm System(EAS) in the iMU. The finalconfiguration provides 8Base Radios per Sector fora total of 24 Radios per Site.

3 Branch Main RFDS Receiver Multi-Coupler (RMC) Specification

The Receiver Multi-Coupler provides three independentchannels which expand a single receive signal into fourports. One output from each four port channel is fed into

a secondary multi-coupler which provides six receive sig-nal outputs per channel. The module contains two hotswappable redundant power supplies (DC/DC convert-ers) connected in parallel with reverse polarity, currentlimit and over-voltage protection. The power supplies con-vert the -48 VDC (input) to a regulated voltage required topower the six Low-Noise Amplifiers (LNAs). The output of

each LNA is then divided equally into four and six isolated ports using a precision balanced re-sistive Power Splitter. The Receiver Multi-Coupler contains all the required monitoring andalarm circuitry for proper operation in the system. A three pin Mate-N-Lock II connector locatedin the rear of the unit is used for the Breaker Panel trip alarm input. This input, along with the

internal Amplifier fail alarm and Power Supply fail alarm are then internally cabled to an 8 pinTELCO jack mounted on the back of the module. This jack provides a compatible connectionwith the Environmental Alarm System (EAS) located in the iMU.

Electrical Specification for Duplexer



Triple Duplexer with VSWR and Power Monitoring Display

The Triple Duplexer consists of three duplexers which pro-vide the required filtering of the transmit (Tx) and Receive

(Rx) signals and allow the transmit and receive signals toshare a common antenna (ANT) port. Each duplexer hasan integrated dual directional coupler which samples theforward (FWD) and reflected (REF) power at the antennaoutput. The sampled FWD and REF power are detected bythe power / VSWR monitoring circuit. A dedicated micro-processor is utilized for each duplexer to accurately cali-brate the measured forward and reflected power readings.The actual forward power and VSWR are then displayed ona backlit LCD display located on the front panel. A sepa-

rate display is provided for each duplexer / antenna port. In addition, the power / VSWR

monitoring circuit generates DC voltages that are proportional to the sampled forward (FWD)and reflected (REF) power level readings. These DC voltages are then fed into the lead baseradios located in the main rack in order to determine the actual forward and reflected powerreadings and interpolate the VSWR for each duplexer / antenna channel.

Electrical & Mechanical Specification

The Hybrid Combiner system combines three transmit paths into onepath using a unique resistive high power combiner structure for threetransmit inputs. The TX1, Tx2 and TX3 transmit outputs are each ap-plied through a dual-stage isolator to the high power combiner hybridwith an integrated low-pass filter. An output on each arm of the powercombiner is terminated into a 150 Watt load. The entire arrangementresults in three transmitter (Tx) input ports per duplexer/ antennabranch. The combiner is installed in a 2U fan cooled tray within therack. Up to two units can be mounted side by side in a the tray unit for a

dual 3:1 combiner configuration. An optional 2-way reactive combiner is also available that mountsin the same tray unit. The 2-way combiner can be used to combine the output of both 3:1 com-biners resulting in six transmitter (Tx) input ports per duplexer/ antenna branch.
