A compact dual-band direct-conversion CMOS transceiver for 802.11a/b/g WLAN

Abstract

A dual-band direct-conversion RF transceiver for IEEE 802.11 a/b/g WLAN is implemented in 0.18 /spl mu/m CMOS technology with 6 mm/sup 2/ die size and 182 mW power dissipation while transmitting 1 dBm at 5 GHz. The receiver achieves 5 dB NF, -8 dBm IIP3 (high LNA gain), 96 dB total gain, and -31.4 dB EVM. The transmitter achieves 1 dBm and 2.5 dBm linear output power at 5 GHz and 2.4 GHz, respectively, with an EVM less than -31 dB.
