摘　　要：本文采用了一种基于优化算法实现的基于优化算法实现的两节双频及三节三频同步匹配变换器TLT设计。该方法是从最基本的理想传输线基本公式,即输入阻抗及相应的反射系数公式出发,采用优化算法求得其解。与Cesar Monzon[4]和Michai[5]介绍的解析方法相比,避免了复杂的推导过程,具有物理概念清晰和简明应用方便等优点。本文还给出了在上述两种情况下的设计参数,证实了本文提出的设计方法是一种简便?有效的工程设计方法。A design method of a two-section ideal transmission line transformer for simultaneously matching two operating frequencies for any transforming ratio, and a three-section ideal transmission line transformer for simultaneously matching three operating frequencies for any transforming ratio is proposed, based on optimization method. And compared to Cesar Monzon and Michai,this methed avoids the complex process of deduction . The results of this study are useful for a number of practical design problems , including dual-band or three-band antennas and RF circuits in general.
