Automated synthesis of multiband matching devices

Abstract

When solving a number of technical problems, it often becomes necessary to create devices that operate in multiple operating frequency bands. This leads to the problem of designing multiband filters, which is solved quite simply with a purely active internal resistance of the signal source and load. In the case when the internal resistance of the signal source and load are complex, Along with this, there is also the problem of coordination. This leads to the need to solve the problem synthesis of broadband multiband circuits connecting complex internal resistance signal source and load. In this paper, the use of methods for constructing a good initial approximations that make it possible to obtain the structure of the eigenfunctions of the device of an adequately problem with subsequent optimization on a computer, allows the synthesis of broadband multiband matching circuits in a lumped element basis for arbitrary admittances signal source and load.
