Title: (EN) Method and apparatus for efficient signal power amplification
(ZH) 高效的信号功率放大方法和装置
Abstract: front page image
(EN) An apparatus (100) uses power recovery from a combining circuit (125) to improve efficiency. A power combiner (125) generates multiple output signals (127, 133) from a combination of input signals (113, 114). One of the output signals from the power combiner is coupled to a power recovery circuit (135), and energy is recovered and preferably stored for later use.
(ZH)

一个装置(100)使用来自组合电路(125)的电功率恢复以改善效率。功率组合器(125)由输入信号生成多个输出信号(127,133)。功率组合器的输出信号中的一个连接到功率恢复电路(135),能量被恢复并且优选地被存储以备后用。
