摘要

文中给出的方法是滑动短路法的改进。它可在实际微波源的任一反射系数下测量方向性

并消除其失配误差;还可快速测量微波源的驻波比和实现对它的匹配。

Abstract

An improvement of the measurement of the directivity of the directional coupler by the sliding short-circuit plunger method is presented. The measurement is carried out at any reflection coefficient of the practical microwave signal source

thus eliminating the mismatch. The method can be used for measuring the voltage standing-wave ratio and tuning match of the microwave signal source quickly.
