行波管发射机幅频均衡技术

Amplitude-Frequency Equalization Technology of TWT Transmitter

均衡是发射机设计和调试过程中的关键工序。介绍行波管(Traveling Wave Tube,TWT)发射机的组成、均衡原理、均衡方式以及均衡注意事项,概述行波管发射机均衡过程涉及的前级放大器、均衡器和末级行波管的工作原理,对比无源均衡和有源均衡两种均衡方式的优缺点,阐述在实际设计和调试过程中如何选择和使用有源均衡器和无源均衡器。

Equalization is the key process in transmitter design and commissioning.This paper mainly introduces the composition,equalization principle,equalization mode of Traveling Wave Tube(TWT)Transmitter and matters needing attention,describes the working principles of amplifiers,equalizers,and traveling wave tubes,compares the advantages and disadvantages of passive equalization and active equalization,and introduces how to select and use active and passive equalizers during design and debugging.
