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, a
