The circular wave guiding structures with various irregularities and layered dielectric filling set a class of devices which are widely used in the microwave equipment. The properties of various irregularities including selective properties allow using them as basic elements at development of various devices of microwave range. In this work the general approach to synthesis of the waveguide filters is considered. The way of receiving initial approach of filter model which can be used for further characteristics optimization is described. As basic elements the circular waveguide cavity resonators with radial metal ridges and dielectric filling are used. The calculation results of S-parameters of the synthesized band-pass filters on circular waveguides are presented.
