Circular Waveguide Filter

Application ID: 16037


A circular waveguide filter is designed using a 2D axisymmetric model. Six annular rings added to the waveguide form circular cavities connected in series, and each cavity cutoff frequency is close to the center frequency of the filter. The simulated S-parameters show a bandpass frequency response.

This model example illustrates applications of this type that would nominally be built using the following products:
