Classification of symmetric two-port networks in relation to the matching theorem and criterion structural synthesis of dissipative-reactive two-port networks

The classification of symmetric two-port networks in relation to the theorem of matching is offered. The classification allows on the initial stages of designing to determine an opportunity and expediency of parametrical optimization of a researched microwave device. The criterion of structural synthesis for search of matching dissipative-reactive two-port networks is offered. The results of work can be used at designing microwave devices a various type - attenuators, phase shifters, filters etc.
