HMC421QS16
PCS/UMTS HIGH IP3 RFIC
DOWNCONVERTER, 1.4 - 2.3 GHz
v01.1102
General Description
Features
Functional Diagram
The HMC421QS16 is a high linearity down-con-
verter receiver IC suitiable for PCS/UMTS infra-
structure 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 ampli-
fi er achieves an Input IP3 of +19 dBm. The con-
verter 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.
