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 Specifi cations, TA = +25° C, LO = -5 dBm, IF = 70 MHz, Vdd = 5V

The circuit board used in the final application should
use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground
leads should be connected directly to the ground
plane similar to that shown. A sufficient number of
via holes should be used to connect the top and
bottom ground planes. The evaluation circuit board
shown is available from Hittite upon request.
