Low-Frequency Schemes of Substitution of Segments Inhomogeneous Transmission Lines

Abstract

The article presents a method for constructing low-frequency equivalent circuits of segments of single and related inhomogeneous transmission lines. Equivalent schemes of segments of inhomogeneous transmission lines are obtained. Obtained expressions make it possible to calculate equivalent D- and T-shaped circuits based on inhomogeneous transmission lines. The cascade connection of such links allows the synthesis of complex matching and filtering devices on non-uniform transmission lines. The resulting set of equivalent circuits on inhomogeneous lines expands the element base for constructing filtering and matching circuits. Chains constructed according to this method can be used both for matching loads (generators) with transmission lines, and for mutual coordination of the generator and the load, as well as for building microwave filters.
