Broadband wireless access will play a dominant role in the development of a mobile information society in the immediate future. Carrier frequencies in the microwave range and modulation schemes producing signals with high crest factors are common to all concepts for the air link. Both in the uplink and in the downlink of a wireless access scheme the power amplifier plays a crucial role: It is responsible for leaving the highly dynamic output signal undistorted while converting the battery power to microwave power at an efficiency as close to 100% as possible. The conflicting demands of linearity, efficiency, cost and performance create enormous technical challenges. This workshop will bring together a variety of perspectives on this challenging theme including device technology, characterization and measurement, circuit/system level modeling and design, architecture and linearization techniques. Part of the presentations will centre on the results of a major new European cooperative research network (TARGET) in RF/Microwave power amplifiers involving some 47 organizations and addressing many of these issues.
