A dual-band triple mode radio compliant with the IEEE 802.11 a/b/g standard implemented in a 0.18 μm CMOS process is presented. The transceiver is compatible with a large number of basebands due to its flexible interface towards AD / DA converters and on-chip automatic calibration of on-chip filters and oscillators. The transceiver achieves a receiver noise figure of 4.9/5.6dB for the 2.4GHz/5GHz bands, respectively, and a minimum transmit error vector magnitude (EVM) of 2.5% for both bands. A quadrature accuracy of 0.3° in phase and 0.05dB in amplitude is achieved through careful analysis and design of the I/Q generation parts of the local oscillator. The local oscillators achieve a better than -34dBc total integrated phase noise. The chip passes ±2kV human body model ESD testing on all pins, including the RF pins. The total die area is 12mm2. The power consumption is 207mW in the receive mode and 247mW in the transmit mode using a 1.8V supply.
