Functional Diagram
General Description
LE
The HMC421QS16 & HMC421QS16E are high
linearity down-converter receiver ICs suitable for
PCS/UMTS infrastructure applications. The receiver
IC is designed to support UMTS applications where
a high third order intercept point (OIP3) is required.
A passive mixer coupled with a high dynamic range
IF amplifier achieves an Input IP3 of +19 dBm. The
converter provides a gain of 8 dB and 9 dB typical
single side band noise. The IC operates from positive
+5V rails and consumes 60 mA of current. The design
requires no external Baluns. The mixer supports IF
frequencies between 50 MHz and 300 MHz.

The circuit board used in the 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.
