A highly integrated, dual-band, multi-mode wireless LAN transceiver

Abstract: A fully integrated radio transceiver chip for the 2.4 and 5 GHz WLAN standards 802.11ah/g is presented in a 0.25 p m 40GHz 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 802.11db/g CCK and OFDM standards. At 2.4 GHz, an operational range of -85 to +8dBm and of -74dBm to +4dBm have been demonstrated for the 11… Show more

“…Recently, a great deal of research has been performed on the development of fullyintegrated multi-band transceivers [4][5][6][7][8]. Most of the published work has focused on the design of circuits which arc traditionally narrow-band, such as low noise amplifiers and voltage-controlled oscillators.…”

“…One of the largest contributors to power dissipation in any RF transceiver is the fre quency divider, which provides channel selection within the frequency synthesizer. Since these circuits are inherently wide-band, traditional multi-band transceivers either operate the divider at the power dissipation required for the highest frequency band, or have em ployed separate dividers for each band of operation [5,8]. While simple, these techniques result either in wasted power dissipation when operating at lower frequencies, or wasted silicon area.…”
