Title: (EN) Apparatus for removing distortions created by an amplifier
(ZH) 用于移除放大器所产生的失真的装置
Abstract: front page image
(EN) A power amplifier has a non-linear low power pre-distortion amplifier (112) for transforming a carrier signal (111) to a pre-distorted signal (113) having a carrier component with out-of-phase non-linear distortions, and a non-linear power amplifier (114) having non-linear characteristics similar to a portion of the non-linear low power pre-distortion amplifier for generating from the pre-distorted signal a transmission signal (115) having an amplified carrier component with substantially diminished non-linear distortions.
(ZH)

一种功率放大器,具有非线性低功率预失真放大器(112),该非线性低功率预失真放大器用于将载波信号(111)变换为预失真信号(113),该预失真信号具有带有异相非线性失真的载波分量,该功率放大器还具有非线性功率放大器(114),该非线性功率放大器具有类似于一部分非线性低功率预失真放大器的非线性特性,它用于从预失真信号中产生传输信号(115),该传输信号具有带有基本上减小的非线性失真的放大载波分量。
