Abstract

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

三模式集成接收器的GPS, GSM 1800，和WCDMA

提出了一种兼容全球定位系统(GPS)、GSM1800和WCDMA的全集成直接转换三模接收机。可配置接收器由带片上匹配网络的宽带低噪声放大器、吉尔伯特单元混频器和动态可重构的gm-C基带滤波器组成。RF和模拟锁在0.18 μ m SiGe技术中占用2.28 mm2。测量结果表明，GPS的噪声系数低至3.2 dB, IIP3为-18 dBm
