Reconfigurable And Cost-Effective FET Mixer
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 -.
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 . 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.
