摘要: A power combining and outphasing system and related techniques for simultaneously providing both wide-bandwidth linear amplification and high average efficiency is described. Providing linear amplification encompasses the ability to dynamically control an RF output power level over a wide range while still operating over a wide frequency bandwidth. The system and techniques described herein also operate to maintain high efficiency across a wide range of output power levels, such that a high average efficiency can be achieved for highly modulated output waveforms.
