摘　　要：L节匹配网络是一种形式简单的微波匹配网络,对于匹配网络的教学有着重要作用。本文针对L节匹配网络的两种形式,推导了各自使用的充要条件,指出了经典教材中的不足。为了进一步理解充要条件的意义,本文结合Smith圆图对上述条件进行了阐述和验证,并基于上述讨论,给出了自制的L节匹配网络程序。L-section matching network is a simple form of microwave matching network,which plays an important role in the teaching.In this paper,the necessary and sufficient conditions are deducedfor application of two forms of L-section matching networks,and the deficiencies in one classic textbook are pointed out.In order to further understand the aforementioned necessary and sufficient conditions,the above conditions are verified by Smith chart.Based on the above discussion,a self-made L-section matching network program is proposed.
