A Single-Chip 5GHz WLAN Transmitter in 0.35μm Si/SiGe BiCMOS Technology

Abstract

This paper deals with the design of a 5GHz WLAN heterodyne transmitter for domotic applications. The transmitter has been realized in commercial 0.35μm Si/SiGe BiCMOS technology with the purpose to reduce cost while achieve an high integration level. Measurements on a prototype, wire-bonded on a low-cost FR4 printed circuit board, have been carried-out showing an overall linear gain of 14dB an input referred compression point of -6.5dBm and a third-order input intercept point of +2.7dBm.

“…With the increasing development of wireless communications, the simple low-cost single chip WLAN 802.11 transceiver is now considered for personal communication terminal applications [3][4][5][6][7]. The future WLAN systems are demanded to increase the link throughout and reliability, the network capacity and the transmit range.…”
