Functional Diagram
General Description
The HMC420QS16 is a linear downconverter
receiver IC suitiable for cellular infrastructure appli-
cations 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 exter-
nal baluns, and minimal off chip components. The
HMC420QS16 has the same package footprint as
the HMC380QS16G & HMC421QS16 1.4 - 2.3 GHz
downconverter ICs.
