Abstract

The invention discloses a four-mode four-pass band filter based on a hemispherical resonant cavity, comprising: a first hemispherical resonant cavity, a second hemispherical resonant cavity, a shelf and two waveguide flanges, wherein the first The waveguide flange is arranged on the upper end of the first hemispherical resonant cavity, the connection between the first waveguide flange and the upper end of the first hemispherical resonant cavity is provided with a first passage port, and the second waveguide method The blue plate is arranged at the lower end of the second hemispherical resonant cavity, and the connection between the second waveguide flange and the lower end of the second hemispherical resonant cavity is provided with a second channel port, and the first channel port A first included angle is formed between the transverse centerline of the second channel opening and the transverse centerline of the second channel opening. The four-mode four-passband filter based on the hemispherical resonator is a filter with high quality factor and multiple passbands.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a four-mode four-pass band filter based on a hemispherical resonant cavity. Background technique [0002] The main function of the filter is to select and filter the transmitted and received frequency signals, and to eliminate unnecessary frequency signals, thereby ensuring the accuracy of the transmitted and received signals. With the rapid development of communication technology today, microwave filters must improve their performance to meet the construction requirements of new communication systems. In the field of communication, circuits often require high quality factor. Specifically, this is to achieve the purpose of low loss and high power in the communication process with high quality factor, and the quality factor of the previous dual-frequency filter is not enough to meet such requirements. . [0003] In practice, spherical cavities have been found to e...
