Abstract
The problem addressed in this paper is reduction of heat dissipation and improvement of dc power usage by increasing the power added efficiency (PAE) and drain efficiency (/spl eta/) of X-band power amplifiers (PAs) to above 60% and 70%, respectively. Adaptive PAs with dynamic biasing and impedance tuning are also discussed.
