A single-chip dual-band tri-mode CMOS transceiver for IEEE 802.11a/b/g WLAN

Abstract

A 2.4/5 GHz transceiver implements the RF and analog front-end of an IEEE 802.11a/g/b WLAN system in 0.25 /spl mu/m CMOS technology. The IC transmits 9 dBm/8 dBm EVM-compliant output power at 5 GHz/2.4 GHz for a 64QAM OFDM signal. The overall receiver NF is 5.5/4.5 dB at 5/2.4 GHz.
