MTT-23: RFIC

2005 RFIC symposium  

Wireless communications, including 2G and 3G cellular, 2.4- and 5-GHz wireless LAN, Bluetooth and GPS, have proliferated rapidly. These forms of communication will not be confined to a single system. In fact, one of the main user requirements is to be able to connect to networks anytime, anywhere using the most suitable wireless system of all the various wireless systems available, according to the situation. This broad requirement has led to a demand for multi-band and multi-mode transceiver ICs. Even though such transceivers feature both multi-band and multi-mode operations, they must be small and economical and have low power consumption. There are various integrated approaches to multi-band ICs, such as parallel RF paths, wideband circuits, multi-pass band circuits, tunable circuits and switching circuits.

This half-day workshop will review these and other techniques for achieving multi-band and multi-mode RFICs, and discuss what the right approach is, in the light of RF performance and cost, at present and in the future.
