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 +9-dBm IIP3 at high gain, and by maintaining LO leakage to the antenna port well below 80~dBm at all gain settings, no external LNA is required. The receiver is fabricated in a 0.25-µm 40-GHz f_t BICMOS technology, and occupies 3mm².
