Asymmetries of intermodulation distortions describe the memory effect of power amplifiers (PAs), but it is hard to measure asymmetries of the phase of the IM components.
交调失真的不对称性描述了功率放大器的记忆特性，但是与幅度相比，交调分量的相位特性很难测量。
The results show that: when two signals are inputted into TWT, the output power includes the intermodulation components, and the intermodulation components have important effect on broadband TWT.
分析结果表明：在多信号输入时，输出功率中确实有输入信号的互调制分量产生，同时可以发现，对于宽频带的行波管，互调制分量对主工作频率输出功率有比较大的影响。
