Based on the mode analysis theory of waveguide resonator,a new class of TM dual-mode waveguide filter is intro-duced in this paper,and the microwave filters are designed by using this kind of resonator.The filter has the characteristics of small size,high Q value and is easy to be tuned and installed.The filter resonators are designed with TM120 and TM210 dual mod-els,and the resonator size can be flexibly designed to meet a variety of requirements.The electromagnetic simulation software is used to design and optimize the filter,and a variety of physical structures are analyzed,including the coaxial structure to achieve input/output filter,high order filter and cavity resonator plane arrangement structure.A Ku-band filter has been manufactured and its performance is excellent,and the test data is consistent with the simulation data.
