摘要

A power recycling technique has been analyzed for efficiency-enhanced radio-frequency (RF) and microwave outphasing power amplifiers for mobile wireless communications. By use of a simple power recycling network, a considerable portion of the wasted power can be recovered back to the power supply, and the enhancement of the overall power efficiency can be achieved without sacrificing the high-linearity performance of the amplifier system. An analysis and calculations have been conducted to optimize the recycling network for the maximum power efficiency. The results predict a significant improvement on the overall power efficiency of the amplifier system for various modulations.
