Abstract

This letter presents a power re-use technique for pulsed oscillating amplifiers. By rectifying the upconverted switching harmonics of the pulsed oscillating output, some portions of wasted power can be returned to the power supply. The efficiency of the amplifier can be enhanced without degradation of the linearity. The measured results show that the overall efficiency of the amplifier with power re-use is improved up to 22% compared to the pulsed oscillating amplifier without the power re-use at the PCS band
