A fully integrated direct conversion tri-mode receiver compliant with Global Positioning System (GPS), GSM1800, and WCDMA is presented. The configurable receiver consists of a wide band low noise amplifier with an on-chip matching network, Gilbert-cell mixers, and dynamically reconfigurable gm-C base-band filters. The RF and analog locks occupy 2.28 mm2 in 0.18 mum SiGe technology. The measurement results show noise figure as low as 3.2 dB for GPS and IIP3 of -18 dBm
