Abstract

This paper presents a low-power single chip WLAN 802.11a transceiver RFIC for personal communication terminal applications. The 5.2GHz transceiver RFIC is implemented in a 0.5μm SiGe technology with 16 mm2die size. It consumes 110/130 mA in receive/transmit mode under a 3.3V supply. The receiver path shows a 6.4dB noise figure and a -20dBm IIP3 under a maximal 67dB gain. The transmitter path IIP3 is measured as 29.7dBm. The LC-tuned VCO has a tuning range from 4.08GHz to 4.7GHz and the measured phase noise is -112dBc/Hz@1MHz offset.
