Dual, SiGe, High-Linearity, 1700MHz to 2200MHz Downconversion Mixer with LO Buffer/Switch
Fully Integrated Downconverter Delivers 6.1dB of Gain, 25.6dBm of IIP3, 9.8dB of NF, and 66dBc of 2LO-2RF Rejection While Replacing 2 Mixers, 4 Amps, 3 Baluns, an LO Switch and Splitter, Plus Dozens of Discretes!
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 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, 6mm x 6mm, 36-pin TQFN package with an exposed paddle. Electrical performance is guaranteed over the extended temperature range, from TC = -40°C to +85°C.
