Active Receive Mixer LF to 3 GHz
The AD8342 is a high performance, broadband active mixer. It is well suited for demanding receive-channel applications that require wide bandwidth on all ports and very low intermodulation distortion and noise figure.
The AD8342 provides a typical conversion gain of 3.7 dB with an RF frequency of 238 MHz. The integrated LO driver presents a 50 Ω input impedance with a low LO drive level, helping to minimize the external component count.
The differential high impedance broadband RF port allows for easy interfacing to both active devices and passive filters. The RF input accepts input signals as large as 1.6 V p-p or 8 dBm (relative to 50 Ω) at P1dB.
The open-collector differential outputs provide excellent balance and can be used with a differential filter or IF amplifier, such as the AD8370, AD8375, AD8351, AD8352, or ADL5561. These outputs can also be converted to a single-ended signal using a matching network or a balun transformer. The outputs are capable of swinging 2 V p-p when biased to the VPOS supply rail.
The AD8342 is fabricated on an Analog Devices, Inc., proprietary, high performance SiGe IC process. The AD8342 is available in a 16-lead LFCSP. It operates over a −40°C to +85°C temperature range. An evaluation board is also available.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
AD8342-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. It requires a 5 V/100 mA power supply for normal operation. The 5 V power supply should be connected to the clip leads VPOS and GND. RF_IN and INLO ports take RF and LO input signals via edge-mounted SMA connectors. The IF port, labeled IF_OUT+, is configured for single-ended signaling via a balun transformer. The board also provides the access for differential IF outputs evaluation.
The purpose of the AD-FREQCVT1-EBZ is frequency up or down conversion to allow the AD9361 to operate down to 1MHz.
Recommended RF/IF Differential Amplifiers
- For differential input/output digital gain amplifier , we recommend the AD8370 or the AD8375 .
- For adjustable gain with external resistor , we recommend the AD8351 .
- For ultralow distortion, pin strappable gain adjust , we recommend the ADL5561 .
- For ultralow distortion and adjustable gain with external resistor , we recommend the AD8352 .
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
