| 摘 要： | 论述了用包络前馈预失真技术实现功率放大器线性化的原理及理论推导过程。预失真器仅仅使用一个输入和输出信号包络的差信号来分别控制矢量调制器中的可调衰减器和可调移相器，以补偿功放的增益和相位的非线性。

| Abstract: | A predistortion linearization method using envelope-feedback technique is proposed and implemented in this paper.This linearizer compensates the gain and phase nonlinearity of power amplifier (PA) by controlling both variable attenuator and phase shifter with only the difference signal between input and output envelopes. |
