三销钉调配器的研究

Research on Three-Stub Tuners

三销钉调配器是一种常用的阻抗调配器,其销钉深度、间距以及销钉的半径均可根据需要进行设置,是大功率微波系统中实现阻抗匹配的常用器件。本文介绍了一种新的分析方法,将每个销钉看作为一个独立的二端口网络,三销钉调配器就相当于三个二端口网络的级联器件,利用其级联规律,可以为三销钉调配器的自动控制提供一种便捷的方法。

Three-stub tuner is an impedance tuner,which is commonly used to realize impedance matching in high power microwave systems.The insertion depth,the spacing and the radius of the pins of three-stub tuners are adjustable according to requirements.This paper introduces a new analysis method of three-stub tuners,in which each pin is regarded as an independent two-port network,and the tuner is a three cascaded two-port network.Utilizing the cascading rule,a convenient automatic control method for three-stub tuner is realized.
