This paper first describes the research background and significance of this paper, understands the importance of microwave millimeter wave frequency band to modern communication technology, divides the microwave frequency band and introduces the characteristics of the corresponding frequency spectrum. The history of microwave millimeter wave, filter and duplex is introduced. The research status of microwave millimeter wave filter and duplex is described by citing the latest research results. Then it introduces the relevant theoretical knowledge of the filter, the classification of the filter and the relevant technical index of the filter, through the introduction of several kinds of normalized low-pass filter prototype, as well as the low-pass prototype to the high-pass, band-pass, The frequency conversion from low pass to band pass is introduced. The coupling between resonators of filter is analyzed and the coupling coefficient and the mode of coupling are understood. Through the above analysis, we have a basic and comprehensive understanding of the relevant theoretical knowledge of the filter. Then, the related knowledge of SIW and the design of SIW millimeter wave filter are introduced in detail. Firstly, the knowledge of rectangular waveguide and SIW is introduced, and the precondition and equivalent formula of the equivalence between rectangular waveguide and SIW are obtained by consulting the data. The transition between the SIW and the external plane structure is introduced. The influence of the through radius, the space between the cavity and the through hole on the resonant frequency and the addition of zero point are obtained by experiments. Finally, the design of V-band millimeter-wave SIW filter is completed. Its passband frequency is 61GHz ~ 66GHz, its volume is 2.64mm 脳 2.64mm 脳 0.24mm and W band millimeter wave SIW filter. Its passband frequency is 95GHz-104GHz, and its volume is 3.4mm 脳 1.36mm 脳 0.134mm. Finally, the related knowledge of the Duplexer and the design of the SIW microwave Duplexer are introduced in detail. The basic knowledge of the Duplexer is introduced first, including the classification of the Duplexer and the design scheme of the filter. It is mainly the series and parallel connection of full complementary duplex and bandpass filter. In the design of microwave duplex, the parallel scheme of bandpass filter is adopted. The design of two bandpass filters with different frequency bands is completed first, and then the two filters are connected in parallel at the input end to complete the final design. The final designed duplex is 7.6GHz-7.8GHz and 8.15GHz-8.35GHz, and the volume is 47.64mm 脳 62mm 脳 0.807mm.
