Design of matching networks

The design of matching network is the task that engineer very often meets in his practice. A large number of work is devoted to this problem but it is still remained actual. It is connected with fact that the classical theory of broadband matching of Bode-Fano-Youla do not permit to take into account a lot of restrictions which are met at practical application of radioelectronic devices. Moreover, this theory generally yields suboptimal results and it is applied only for relatively simple load structure. However, the analytic theory is fundamental importance for understanding matching problems. The main numerical methods are considered in the present work. A brief description of operation and comparative characteristics are given.
