This paper presents a single-chip dual-band CMOS direct-conversion transceiver fully compliant with the IEEE 802.11a/b/g standards. Operating in the frequency ranges of 2.412-2.484 GHz and 4.92-5.805 GHz (including the Japanese band), the fractional-N PLL based frequency synthesizer achieves an integrated (10 kHz-10 MHz) phase noise of 0.54 degree /1.1 degree for 2/5-GHz band. The transmitter error vector magnitude (EVM) is -36/-33 dB with an output power level higher than -3/-5dBm and the receiver sensitivity is -75/-74 dBm for 2/5-GHz band for 64QAM at 54 Mb/s.
