General Description

The MAX2042A single, high-linearity upconversion/downconversion mixer provides up to +33dBm input IP3, 7.25dB noise figure, and 7.2dB conversion loss for 1600MHz to 3900MHz GSM/EDGE, CDMA, TD-SCDMA, WCDMA, LTE, TD-LTE, WiMAXK, and MMDS wireless infrastructure applications. With an ultra-wide 1300MHz to 4000MHz LO frequency range, the IC can be used in either low-side or high-side LO injection architectures for virtually all 1.7GHz to 3.5GHz applications (for a 2.5GHz variant tuned specifically for low-side LO injection, refer to the MAX2042).

In addition to offering excellent linearity and noise performance, the IC also yields a high level of component integration. This device includes a double-balanced passive mixer core, an LO buffer, and on-chip baluns that allow for single-ended RF and LO inputs. The IC requires a nominal LO drive of 0dBm, and supply current is typically 140mA at VCC = 5.0V or 122mA at VCC = 3.3V.

The MAX2042A is pin compatible with the MAX2042 2000MHz to 3000MHz mixer. The MAX2042A is also pin similar with the MAX2029/MAX2031/MAX2033 650MHz to 1550MHz mixers, the MAX2039/MAX2041 1700MHz to 3000MHz mixers, and the MAX2044 2300MHz to 4000MHz mixer, making the entire family of upconverters/downconverters ideal for applications where a common PCB layout is used for multiple frequency bands.

The MAX2042A is available in a compact, 20-pin TQFN package (5mm x 5mm) with an exposed pad. Electrical performance is guaranteed over the extended TC = -40NC to +85NC temperature range.

ABSOLUTE MAXIMUM RATINGS

Note 1: TC is the temperature on the exposed pad of the package. TA is the ambient temperature of the device and PCB.Note 2: Based on junction temperature TJ = TC + (BJC x VCC x ICC). This formula can be used when the temperature of the

exposed pad is known while the device is soldered down to a PCB. See the Applications Information section for details. The junction temperature must not exceed +150NC.

Note 3: Junction temperature TJ = TA + (BJA x VCC x ICC). This formula can be used when the ambient temperature of the PCB is known. The junction temperature must not exceed +150NC.

Note 4: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 5: Not production tested.Note 6: Operation outside this range is possible, but with degraded performance of some parameters. See the Typical Operating

Characteristics.Note 7: All limits reflect losses of external components, including a 0.5dB loss at fIF = 300MHz due to the 1:1 impedance

transformer. Output measurements were taken at IF outputs of the Typical Application Circuit.Note 8: 100% production tested for functional performance.Note 9: Measured with external LO source noise filtered so that the noise floor is -174dBm/Hz at 100MHz offset. This specification

reflects the effects of all SNR degradations in the mixer including the LO noise, as defined in Application Note 2021: Specifications and Measurement of Local Oscillator Noise in Integrated Circuit Base Station Mixers.

Note 10: Maximum reliable continuous input power applied to the RF or IF port of this device is +12dBm from a 50I source.

Upconversion/Downconversion Mixer with LO BufferFunctional Diagram

Detailed Description

When used as a high-side LO injection mixer in the 2300MHz to 2900MHz band, the MAX2042A provides +33dBm of IIP3, with typical conversion loss and noise figure values of only 7.2dB and 7.25dB, respectively. The integrated baluns and matching circuitry allow for 50I single-ended interfaces to the RF and the LO port. The integrated LO buffer provides a high drive level to the mixer core, reducing the LO drive required at the IC’s input to a -6dBm to +3dBm range. The IF port incor-porates a differential output, which is ideal for providing enhanced 2LO - 2RF performance.

Specifications are over broad frequency ranges to allow for use in GSM/EDGE, CDMA, TD-SCDMA, WCDMA, LTE, TD-LTE, WiMAX, and MMDS base stations. The device is specified to operate over a 1600MHz to 3900MHz RF input range, a 1300MHz to 4000MHz LO range, and a 50MHz to 500MHz IF range. The external IF components set the lower frequency range (see the Typical Operating Characteristics for details). Operation beyond these ranges is possible (see the Typical Operating Characteristics for additional information).

RF Input and BalunThe IC’s RF input provides a 50I match when combined with a series DC-blocking capacitor. This DC-blocking capacitor is required as the input is internally DC shorted to ground through the on-chip balun. When using an 8.2pF DC-blocking capacitor, the RF port input return loss is typically 17dB over the 2300MHz to 2900MHz

RF frequency range. A return loss of 14dB over the 3000MHz to 3900MHz range is achieved by changing the DC-blocking capacitor to 1.5pF.

For applications spanning the 1700MHz to 2200MHz frequency range, a 12nH shunt inductor can be used in conjunction with a 1.8pF DC-blocking capacitor to provide a typical return loss of 12dB. See the Typical Application Circuit and Table 1 for details.

LO Inputs, Buffer, and BalunWith a broadband LO drive circuit spanning 1300MHz to 4000MHz, the device can be used in either low- or high-side LO injection architectures for virtually all 1.7GHz to 3.5GHz receiver and transmitter applications. The LO input is internally matched to 50I, requiring only a 2pF DC-blocking capacitor. A two-stage internal LO buffer allows for a -6dBm to +3dBm LO input power range. The on-chip low-loss balun, along with an LO buffer, drives the double-balanced mixer. All interfacing and match-ing components from the LO inputs to the IF outputs are integrated on-chip.

High-Linearity MixerThe core of the device is a double-balanced, high- performance passive mixer. Exceptional linearity is provided by the large LO swing from the on-chip LO buffer. IIP3, 2LO - 2RF rejection, and noise-figure performance are typically 33dBm, 72dBc, and 7.25dB, respectively.

Differential IF PortsThe device has a 50MHz to 500MHz IF frequency range, where the low-end frequency depends on the frequency response of the external IF components.

The device’s differential IF ports are ideal for providing enhanced 2LO - 2RF performance. The user can connect a differential IF amplifier or SAW filter to the mixer IF port, but a DC block is required on both IF+/IF- ports to keep external DC from entering the IF ports of the mixer. To characterize the part, an external MABACT0069 1:1 transformer is used to transform the 50I differential IF interface to 50I single-ended. Its loss is included in the data presented in this data sheet. This transformer also supplies a needed IF pin ground return for the on-chip circuitry. If a ground return is not available on the IF pins, the return is achievable through some off-chip resistance to ground or large-value inductors. A 1kI to ground on each IF pin can be used for such an application. In addition, the IF interface directly supports single-ended, AC-coupled signals into or out of IF+ by shorting IF- to ground and using a 1kI resistor from IF+ to ground.

Upconversion/Downconversion Mixer with LO BufferApplications Information

Input and Output MatchingThe RF input provides a 50I match when combined with a series DC-blocking capacitor. Use an 8.2pF capac-itor value for RF frequencies ranging from 2000MHz to 2900MHz. Use a 1.5pF capacitor value to match the RF port for the 3000MHz to 3900MHz band. For RF frequencies in the 1650MHz to 2250MHz range, use C1 = 1.8pF and L1 = 12nH. The LO input is internally matched to 50I, so use a 2pF DC-blocking capacitor to cover operations spanning the 1300MHz to 4000MHz range. The IF output impedance is 50I (differential). For evaluation, an external low-loss 1:1 (impedance ratio) balun transforms this impedance down to a 50I single-ended output (see the Typical Application Circuit).

Reduced-Power ModeThe device includes a pin (LOBIAS) that allows an exter-nal resistor to set the internal bias current. A nominal value for this resistor is given in Tables 1 and 2. Larger-value resistors can be used to reduce power dissipa-tion at the expense of some performance loss. If Q1% resistors are not readily available, substitute with Q5% resistors.

Significant reductions in power consumption can also be realized by operating the mixer with an optional supply voltage of 3.3V. Doing so reduces the overall power consumption by up to 42%. See the 3.3V Supply AC Electrical Characteristics tables and the relevant 3.3V curves in the Typical Operating Characteristics section to evaluate the power vs. performance tradeoffs.

Layout ConsiderationsA properly designed PCB is an essential part of any RF/microwave circuit. Keep RF signal lines as short as possible to reduce losses, radiation, and inductance. For the best performance, route the ground pin traces directly to the exposed pad under the package. The PCB exposed pad MUST be connected to the ground plane of the PCB. It is suggested that multiple vias be used to connect this pad to the lower-level ground planes. This method provides a good RF/thermal conduction path for the device. Solder the exposed pad on the bottom of the device package to the PCB.

Power-Supply BypassingProper voltage-supply bypassing is essential for high-frequency circuit stability. Bypass each VCC pin with the capacitors shown in the Typical Application Circuit and see Table 1.

Exposed Pad RF/Thermal Considerations

The exposed pad (EP) of the device’s 20-pin TQFN package provides a low thermal-resistance path to the die. It is important that the PCB on which the device is mounted be designed to conduct heat from the EP. In addition, provide the EP with a low-inductance path to electrical ground. The EP MUST be soldered to a ground plane on the PCB, either directly or through an array of plated via holes.
