The method of specifying filter characteristics could vary among equipment designers.

The L-C circuit configurations for lumped RF filters are presented with the functioning of the circuits. The concept of semi-lumped RF filter, resonance in microwave coaxial cavity, combline and iriscoupled cavity filters are technologies are explained in detail. Information regarding power handling capacity, equivalent circuit and factors to minimise insertion loss of cavity filters are provided. The basic microstrip and stripline circuit and the computer aids for designing the filters are also explained.

End resonant cavity sections are coupled to input/output coaxial connectors. Combline and iris-coupled microwave cavity filters are quite popular in industrial applications. Combline filters use k/8 resonators and iris-coupled filters use k/4 resonators at resonant frequency. 2 Combline and Iris-Coupled Cavity Filters In microwave cavity filters, air is the dielectric medium of transmission and the filters do not require any dielectric support. The filters are characterised by low insertion loss with high rejection making them suitable for high power applications.
