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 ampli-
fiers. 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 × 6mm) with an exposed paddle.
Electrical performance is guaranteed over the extended
temperature range, from T
19-3383; Rev 0; 8/04
Dual, SiGe, High-Linearity, 1700MHz to 2200MHz
