摘要
本文提出了多端口网络的广义匹配理论,并给出了具体的实现方法.研究表明:多端口网络要满足全匹配,则必须牺牲端口间的传输作为付出代价.特别在N口全对称网络情况下,传输系数模值得满足不等式约束.此外,本文还发现三口互易网络的广义匹配由无耗转向有耗时会发生突变现象,很值得进一步探讨.
A kind of generalized matching theory is proposed for multi-port networks,and the concrete method for realizing is given. The study shows that to perfectly match a network, the transmission of the network must be sacrificed in certain degree. Particularly,if the network is complete symmetrical,the module of transmission coefficient should satisfy the unequality |β|<1/(N- 1). In addition,we found the phenomenon that sudden changes will occur in the generalized matching of three-port reciprocal networks when the network changes from lossy to lossless,which deserves a further research.
