Description/Abstract

This paper describes a highly integrated CDMA 2000 US-CEL band (880-MHz) receiver. The single-chip zero-IF design incorporates all receiver signal-path functions including the low-noise amplifier (LNA) on a single die. The complete receiver design exceeds the stringent linearity and local oscillator (LO) leakage requirements for this standard arising from the coexistence with narrow-band FM signals. The integrated LNA achieves 1.0-dB noise figure with $+hbox9-dBm$IIP3 at high gain, and by maintaining LO leakage to the antenna port well below $-hbox80~dBm$ at all gain settings, no external LNA is required. The receiver is fabricated in a 0.25-$muhboxm$40-GHz$f_t$BICMOS technology, and occupies 3$hboxmm^2$.
