The article presents a design for a bandpass filter using TE dual-mode resonator. The design is based on the general scatting matrix of each discontinuity in the structure. Different propagation modes in the same waveguide section are used to represent the matrices to facilitate the design. On the basis of ultra-high frequency theory and simulation software tools, the authors have calculated the design of a 4th order bandpass filter using the resonances, and with two symmetrical transmission zeros.
