General Description
The HMC377QS16G is a linear downconverter
receiver IC suitiable for cellular infrastructure
applications from 0.8 - 1.0 GHz. An integrated mixer
coupled with a high dynamic range IF ampli鏗乪r
achieves an input intercept point (IP3) of +15 dBm,
and an input P1dB of +3.5 dBm. The converter
provides a gain of 13.5 dB and only 11 dB typical
single side band noise 鏗乬ure. The IC operates from
a positive +5V rail consuming 135 mA of current
while requiring only -5 dBm LO drive. The design
requires no external baluns. The mixer supports IF
frequencies between 50 MHz and 250 MHz.
