Abstract

A 3.3 v 150 mW IF IC is implemented using 0.8 μm CMOS process. This IC integrates both CDMA and FM IF signal processing units and interfaces between IF signals and baseband modem. Rx mixer down-converts 85.38 MHz IF signals into baseband signal, and Tx mixer based on a replica transconductor up-converts baseband signal into a 130.38 MHz IF signal. The chip size is 5.5×6.3 mm².
