Dual, SiGe, High-Linearity, 1700MHz to 2700MHz Downconversion Mixer with LO Buffer/Switch

Lowest Noise, Highest Linearity, Dual, 1700MHz to 2700MHz SiGe Mixer for 2.5G and 3G Base Stations

Product Details

The MAX9995 dual, high-linearity, downconversion mixer provides 6.1dB gain, +25.6dBm IIP3, and 9.8dB NF for WCDMA, TD-SCDMA, LTE, TD-LTE, and GSM/EDGE base-station applications.

This device integrates baluns in the RF and LO ports, a dual-input LO selectable switch, an LO buffer, two double-balanced 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 TQFN package (6mm × 6mm) with an exposed pad. Electrical performance is guaranteed over the extended temperature range, from TC = -40°C to +100°C.
