摘要

包络跟踪、包络消除和恢复等放大技术提高了电信系统无线电发射机的效率。然而，在这些方法中使用的调制电源会给射频信号带来失真。本文建立了调制电源参数对包络信号中寄生谐波水平的影响程度，而寄生谐波会导致射频信号失真。

Impact of Modulated Power Supply Parameters on its Output Voltage Distortions

Amplification techniques such as envelope tracking and envelope elimination and restoration improve the efficiency of a radio transmitter of a telecommunication system. However, the modulated power supply used in these methods can introduce distortion into the RF signal. This article establishes the degree to which the parameters of a modulated power supply influence the level of parasitic harmonics in the envelope signal, which can cause distortion of the RF signal.
