Abstract
A dual-band trimode radio fully compliant with the IEEE 802.11a, b, and g standards is implemented in a 0.18-/spl mu/m CMOS process and packaged in a 48-pin QFN package. The transceiver achieves a receiver noise figure of 4.9/5.6 dB for the 2.4-GHz/5-GHz bands, respectively, and a transmit error vector magnitude (EVM) of 2.5% for both bands. The transmit output power is digitally controlled, allowing per-packet power control as required by the forthcoming 802.11 h standard. A quadrature accuracy of 0.3/spl deg/ in phase and 0.05 dB in amplitude is achieved through careful analysis and design of the I/Q generation parts of the local oscillator. The local oscillators achieve a total integrated phase noise of better than -34 dBc. Compatibility with multiple baseband chips is ensured by flexible interfaces toward the A/D and D/A converters, as well as a calibration scheme not requiring any baseband support. The chip passes /spl plusmn/2 kV human body model ESD testing on all pins, including the RF pins. The total die area is 12 mm/sup 2/. The power consumption is 207 mW in the receive mode and 247 mW in the transmit mode using a 1.8-V supply.Keywords
