Abstract

A single-chip cdma-2000 zero-IF transceiver has been successfully developed for band-class 4 (Korean-PCS band) with an additional GPS signal receiving functionality. The receiver showed excellent noise and linearity performance (full- path NF=2dB, IIP3=-6dBm) with very low phase-noise VCO (- 132dBc/Hz@1.25MHz/f_OSC=3.71G). The Tx-Rx isolation turned out to be good enough for the sensitivity and single-tone desensitization requirement of the CDMA-2000 system. The IC was implemented on a 0.35mum SiGe BiCMOS technology.
