RF front-end for HIPERLAN

Neel Natekar, Vasudha Vasudevan, Anupam Viswanath

Abstract

5.2 GHz band is used by IEEE 802.11 and High performance Radio Local Area Network (HIPERLAN) systems. In this work we design a front end receiver with baseband amplifier for these systems. This receiver employs a dual conversion heterodyne architecture. We plan to design with an IF of 2.6 GHz. We aim to show the advantage of this frequency scheme which obviates the need for an image reject filter. We plan to resolve the issues of LO-IF feed through, maintaining high Signal to Noise ratio (SNR), low distortion in designing these blocks.
