Functional Diagram
General Description
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.
