    The multicarrier receiver IC described in this paper receives four adjacent WCDMA channels simultaneously in order to reduce the component count of a base-station. The receiver uses low-IF architecture and it is fabricated with a 0.25-μm SiGe BiCMOS process to meet the high-performance requirements set by the base-station application. The receiver Includes a dual-input low-noise amplifier (LNA), quadrature mixers, a local-oscillator (LO) divider, IIP2 calibration circuits, 10-MHz low-pass filters, and ADC buffers. The receiver noise figures, measured over the downconverted WCDMA channels centered at 2.5-MHz and 7.5-MHz Intermediate frequencies, are 3.0 dB and 2.6 dB, respectively. The receiver achieves 47-dB voltage gain and -12-dBm out-of-band IIP3 and consumes 535 mW from a 2.5-V supply.
