Functional Diagram
General Description
The HMC377QS16G & HMC377QS16GE are linear
downconverter receiver ICs suitable for cellular
infrastructure applications from 0.8 - 1.0 GHz. An
integrated mixer coupled with a high dynamic range
IF amplifier 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 figure. 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.
Electrical Specifications, T_A = +25° C, LO = -5 dBm, IF = 70 MHz, Vdd = 5V
