SYNTHESIS OF MICROSTRIP MICROWAVE FILTERS WITH ATTENUATION POLES AT ENDING FREQUENCIES

摘要

A method of synthesis of microwave filters with attenuation poles is proposed. The obtained relations make it possible to efficiently solve the problem of microstrip microwave filters implementation with due account for their design features, bypassing the stage of transfer function approximation and construction. Topologies of the fourth- and ninth-order microstrip filters in the form of a nonsymmetrical microstrip line and some MSL configurations for designing such filters are proposed. The work was performed within the Federal program "Scientific and Pedagogical Human Resources of the Innovative Russia" for 2009-2013.
