Abstract :
A fully integrated radio transceiver chip for the 2.4 and 5 GHz WLAN standards 802.11a/b/g is presented in a 0.25 /spl mu/m 40 GHz BiCMOS technology. The chip integrates the LNAs, mixers, channel filters, PGC, synthesizers with VCOs and reference oscillator, transmitters, anti-aliasing filters and voltage regulators. The presented transceiver exceeds all IEEE requirements for the 802.11a/b/g CCK and OFDM standards. At 2.4 GHz, an operational range of -85 to +8 dBm and of -74 dBm to +4dBm have been demonstrated for the 11 Mb/s CCK and 54Mb/s OFDM modes, respectively. Furthermore a maximum EVM of -32 dB have been measured.
