A fully CMOS integrated RF transceiver for IEEE 802.11b wireless LAN application is implemented and measured. The IC is fabricated in 0.25 μm CMOS process and packaged in TQFP package. The single chip transceiver incorporates an I/Q modulator and demodulator, an integrated IF and RF synthesizer with on-chip VCO, an on-chip LNA, and PA pre-driver amplifier. The chip fully complies with the IEEE 802.11b WLAN standard. The transmitter achieves less than 7.5% EVM and the receiver sensitivity is -86 dBm for 11 Mbit/s mode. The chip uses 3V power supply and the current consumption is 60 mA for receiver and 70 mA for transmitter.
