Abstract :
This paper presents a wideband wireless digital PHY/MAC chip which processes 90 MHz of bandwidth and integrates three fully asynchronous 802.11 a/b/g compliant modems delivering a peak data rate of 162 Mb/s. The 70.55 mm2 IC in 0.18 μm CMOS technology features a near-far DR of 45 dB for 54 Mb/s signals, OFDM (CCK) transmit SNR of 68 db (77 dB) and a spectrum monitor with 1.4 MHz resolution at 250 kHz.
