    Abstract

    A direct conversion RF front-end for 2.0-GHz WCDMA and 5.8-GHz WLAN applications is described. The measured double-sideband NF, IIP3 and voltage gain are 3.6 dB, -15.1 dBm and 29.5 dB for WCDMA, and 5.2 dB, -17.4 dBm and 26. 5 dB for WLAN, respectively. The RF front-end consumes 22.3 mA in WCDMA mode and 23.1 mA in WLAN mode from a 2.7-V supply. The chip is fabricated using a 0.35-μm 45-GHz SiGe BiCMOS process.
