Abstract
—In this paper an all metallic band pass filter with high power handling capability is proposed. The operating frequency bandwidth of the design can be determined by tuning the proposed modulation parameters of the ridge in the waveguide. As a proof of concept, a bandwidth from 11GHz up to 29GHz is selected to force the waveguide to operate in single mode scenario to mitigate multi mode dispersion by simply adding a transition from ridge waveguide to a normal one.
