General Description
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 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 TQFN
package (6mm × 6mm) with an exposed pad. Electrical
performance is guaranteed over the extended tempera-
ture range, from T
C
= -40°C to +100°C.
