Silicon UTSi/sup (R)/ CMOS RFIC for CDMA wireless communications systems

Design and performance of UTSi CMOS down converter RFIC for CDMA applications is presented. The down converter consists of a two-stage LNA, RF switch, and mixer integrated with passive matching components. Performance of building blocks have been evaluated. Results show that the stringent requirements for linearity at low power consumption required for CDMA can be achieved using UTSi CMOS technology. By integrating the down converter with PLL fabricated in the same process, it will be possible to realize a single chip transceiver IC. Results show that silicon CMOS UTSi has the on-chip RF performance required for high level of integration of future wireless communications systems.
