Abstract

An RF front-end for dual-band, dual-mode operation is presented in this paper. The front-end consumes 22.5 mW from a 1.8 V supply and is designed to be used in direct conversion WCDMA and GSM receivers. The measured noise figure, gain, and IIP3 are 2.3 dB, 39.5 dB, and -19 dBm for GSM and 4.3 dB, 33 dB, and -14.5 dBm for WCDMA, respectively. The front-end has 27 dB gain control range in both systems.

用于WCDMA和GSM应用的双频射频前端

本文提出了一种适用于双频双模工作的射频前端。前端从1.8 V电源消耗22.5 mW，设计用于直接转换WCDMA和GSM接收器。GSM的噪声系数、增益和IIP3分别为2.3 dB、39.5 dB和-19 dBm, WCDMA的噪声系数、增益和IIP3分别为4.3 dB、33 dB和-14.5 dBm。两种系统的前端增益控制范围均为27db。
