摘要

结果表明，当一个双音信号和一个由不同混频分量组成的信号通过非线性无记忆放大器输出时，输入和输出信号中基频分量的相量与输出信号中三阶互调分量的相量之间存在一定的关系。这种关系会产生一种有趣的效果。在输出信号中，同时取消IMD3积，恢复基波分量相量的比值。

Proof of a relation between phasors of certain harmonic components of memoryless amplifier output signal

It is shown that there holds a relation between the phasors of fundamental components, in the input and output signals, and the phasors of the third order intermodulation (IMD3) components of the output signal, when a sum of a two-tone signal and a signal consisting of components at difference mixing frequencies is sent through a nonlinear memoryless amplifier. This relation can result in an interesting effect. In the output signal, simultaneously the IMD3 products are cancelled and the ratio of the phasors of fundamental components is restored.
