BiCMOS Radio-Frequency Front-Ends
for Wireless-LAN Receivers.


2006; 234 pages. € 64,00.

ISBN 3-86628-071-8





This work presents the study of the design of the RF front-end for monolithic receivers, which are compliant with the wireless LAN standards at 5GHz, and the modifications needed for dual-band extension to the 2GHz band. In particular, the implementation in BiCMOS technologies has been considered, since these are well suited for the large-scale fabrication of low-cost system-on-chip.

The design of low-noise amplifiers, microwave mixers and polyphase filters is studied in detail. Several design examples are given for individual circuits suitable for monolithic integration.

The choices made for the various building blocks and architectures are validated experimentally by presenting several integrated RF front-ends. Two low-IF receivers meet the specifications for 5-6GHz, and a dual-band version allows operation also at 2.4GHz. All the circuits operate with very low power consumption.


Corrado Carta received the Laurea in Ingegneria Elettronica (Master's Degree in Electrical Engineering) from the University of Cagliari, Italy, in April 2000. Since July 2000 he has been with the Electromagnetic Fields and Microwave Electronics Laboratory of the Swiss Federal Institute of Technology (ETH), Zurich, Switzerland, where he worked in the area of low-power radio-frequency integrated circuits for wireless-LAN applications.
