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.  
Electrical Specifications, TA = +25 °C, LO = +10 dBm, Vdd = 5V
