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.
