An 802.11a/b/g RF Transceiver in an SoC

The RF transceiver of a 0.13mum CMOS WLAN 802.11 a/b/g SoC for cellular applications comprising MAC, PHY, and analog front-end is presented. The transceiver with direct-conversion architecture and broadband 12GHz VCO draws 87/104mA in TX and 69/80mA in RX mode for the 2.4/5.0GHz band. The TX with control loop achieves -32dB EVM at -2dBm output power with 1.5V supply.
