The MAX9995 dual, high-linearity, downconversion mixer provides 6.1dB gain, +25.6dBm IIP3, and 9.8dB NF for UMTS/WCDMA, DCS, and PCS base-station applications. The MAX9995 is ideal for low-side LO injection. (For a mixer variant optimized for high-side LO injection, contact the factory.)

This device integrates baluns in the RF and LO ports, a dual-input LO selectable switch, an LO buffer, two doublebalanced mixers, and a pair of differential IF output amplifiers. The MAX9995 requires a typical LO drive of 0dBm and supply current is guaranteed to be below 380mA.

These devices are available in a compact 36-pin thin QFN package (6mm x 6mm) with an exposed paddle. Electrical performance is guaranteed over the extended temperature range, from T_C = -40°C to +85°C.

An evaluation kit is available: MAX9995EVKIT
