本文叙述的射频变量器由长度与特性阻抗相等的匹配传输线所组成。传输线的连接按照教科书中所给的方法。这种变量器具有很宽广的频率响应,而且很容易计算。文章介绍两种分析方法。计算与测试结果完全一致。
The RF variable described in this article is composed of matching transmission lines with the same length and characteristic impedance. The connection of the transmission line follows the method given in the textbook. This variable device has a wide frequency response and is easy to calculate. The article introduces two methods of analysis. Computation and test results are exactly the same.
