宽带匹配网络的有限直接设计法

Limited Direct Designing Method of Broad-Band Matching Network

本文就宽带匹配网络的设计问题,阐述了网络的转换功率增益特性与梯形网络之间的关系。针对实用的梯形匹配网络结构,给出了适合于计算机求解的增益表达式,并提出梯形匹配网络的机助设计方法——有限直接设计法。依据这一方法编成的计算机程序BOMB,可以简便地设计单端匹配、双端匹配所需的梯形网络。文中给出一些比较性算例和实际匹配网络的设计结果,表明这一方法的可行性。

For studying the broad-band matching ploblem, the transducer power gain of ladder networks are discussed in this paper. The gain expressions, which are suitable analysed by the aid of a computer, for the practical constructions of the ladder networks are given, and the limited direct designing method, a new procedure of the computer-aided design of broad-band matching network is presented. Computer program BOMB which is based on this method can be conveniently applied to design the ladder network for simple and double matching problem. Some design examples are given to show the feasibility of this method.
