Abstract

A transceiver for 802.11 a/b/g access points supports MRC diversity resulting in a 3dB static sensitivity improvement over a single-receiver implementation. A closed-loop transmit power control scheme achieves 0.5dB accuracy. Receive ADCs and transmit DACs are included, allowing autonomous AGC and transmit power control loops and an all-digital modem/MAC IC. The 25mm² IC is fabricated in a 0.18mum CMOS process and achieves 3.9dB/4.5dB (low-band/high-band) receive NF and less than -35dB transmit EVM
