Functional Diagram
General Description
The HMC420QS16 & HMC420QS16E are linear
downconverter receiver ICs suitable for cellular
infrastructure applications from 0.7 - 1.0 GHz. An
integrated mixer coupled with a high dynamic range
IF amplifier achieves an input intercept point (OIP3) of
+15 dBm, and an input P1dB of +1 dBm. The converter
provides a gain of 12.5 dB and 13 dB typical single
side band noise. The IC operates from positive +5V
rails consuming 52 mA of current while requiring only 0
dBm LO drive. The design requires no external baluns,
and minimal off chip components. The HMC420QS16
& HMC420QS16E have the same package footprint
as the HMC380QS16G & HMC421QS16 1.4 - 2.3 GHz
downconverter ICs.

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.
