Abstract :
Some aspects of designing lowpass and bandpass evanescent-mode filters based on single-and double-ridge waveguides are discussed. It is demonstrated that an introduction of the new type of transformers allows to obtain the lowpass filter configurations providing wide pass and stop bands. The improved procedure of initial synthesis of bandpass filters permits to obtain their geometry for pass bands up to 20% and extended stop band.
