Abstract :
An 802.11 a/b/g wireless LAN SoC for low-power embedded applications is implemented in a 0.18mum CMOS technology. The IC integrates the RF transceiver, digital PHY and MAC, CPU and host interface. For 64QAM OFDM, the 5GHz/2.4GHz TX EVM is -27.4dB/-27.5dB at an output power of -5.2dBm/-3.5dBm. Overall 5GHz/2.4GHz RX sensitivity is -73dBm/-76dBm at 54Mb/s
