Generalized filter theory operates with resonant frequencies and coupling coefficients of coupled resonators in a microwave filter. Lumped-element LC filters [ edit ] The simplest resonator structure that can be used in rf and microwave filters is an LC tank circuit consisting of parallel.

The lines can be either circular rods or rectangular bars, and interfacing to a coaxial format line is easy. As with the parallel-coupled line filter, the advantage of a mechanical arrangement that does not require insulators for support is that dielectric losses are eliminated.The structure of the filter consists of electromagnetically coupled meandered-line symmetric stepped-impedance resonators.

The strength of the coupling between the resonators is enhanced by using a meandered-line stub-load inside the resonators to improve the selectivity and miniaturize the size of the : Z.
