A single chip CMOS transceiver for 802.11 a/b/g WLANs

Abstract

A 0.18 /spl mu/m dual-band tri-mode CMOS radio, fully compliant with the IEEE 802.11 a/b/g standards, achieves a system noise figure of 5.2/5.6 dB (high gain), and an EVM of 2.7/3.0% for the 2.4/5 GHz bands, respectively. Die area is 12 mm/sup 2/, and power consumption is 200 mW in RX and 240 mW in TX using a 1.8 V supply.
