Reconfigurable And Cost-Effective FET Mixer

1. Introduction

The rapid growth of the wireless communication systems and the transition from the second (2G) to third (3G) and later generations makes the requirement of multi-mode, multi-band, and multi-standard transreceivers integration on the portables for communication irrespective of the geographical boundary [1]-[10].

These transitions create the necessity for reconfigurable transreceiver system, which can support and handle higher data rates to process GSM, 3G, WiMAX and LTE in a miniaturized size [1]. The selection criteria of a reconfigurable transreceiver system is challenging because performance trades in with the costs, power consumption and integrability.

A typical homodyne (zero-IF receiver) requires less functional blocks compared with the super-heterodyne architecture, but at the cost of selectivity performances. Therefore, performance and the cost matrix drive the receiver architecture in market place.
