Abstract :
This paper presents a low-power single chip WLAN 802.11a transceiver RFIC for personal communication terminal applications. The 5.2 GHz transceiver RFIC is implemented in a 0.5 mum SiGe technology with 16 mm2 die size. It consumes 110/130 mA in receive/transmit mode under a 3.3V supply. The receiver path shows a 6.4 dB noise figure and a -20dBm IIP3 under a maximal 67 dB gain. The transmitter path IIP3 is measured as 29.7 dBm. The LC-tuned VCO has a tuning range from 4.08 GHz to 4.7 GHz and the measured phase noise is - 112 dBc/Hz @ 1MHz offset.
