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 Vp-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 2Vp-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.

Product Lifecycle Recommended for New Designs
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.
Evaluation Kits (2)
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 AD-FREQCVT1-EBZ is an add on board for the FMCOMMS3/4/5 boards which contain the AD9361. While the complete chip level design package can be found on the ADI product pages, information on the card, how to use it, the design package that surrounds it, and the software which can make it work, can be found on the analog wiki site.
The purpose of the AD-FREQCVT1-EBZ is frequency up or down conversion to allow the AD9361 to operate down to 1MHz.

Tools & Simulations
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
