Abstract

The embodiment of the invention discloses and provides a small-sized microwave dielectric dual-mode filter which comprises a plurality of resonant cavities connected in series. A metal diaphragm is arranged between every two adjacent resonant cavities, and coupling is carried out through coupling hole structures on the metal diaphragm; the first resonant cavity and the last resonant cavity in the plurality of resonant cavities connected in series are metal resonant cavities, and the rest resonant cavities are metal-medium resonant cavities; each metal resonant cavity comprises a metal shell, a metal resonator arranged in the metal shell and a connector arranged on the metal shell, a tap line is arranged in the connector, and the tap line is connected with the metal resonator; and each metal-medium resonant cavity comprises a ceramic medium block and a metal sleeve, the ceramic medium block is embedded on the metal sleeve, and the ceramic medium block is provided with a plurality of coupling structures so that the performances of small volume, compactness, low loss and large power capacity are realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a small microwave dielectric double-mode filter. Background technique [0002] With the development of wireless communication technology, especially the arrival of the 5G era, the 5G large-scale antenna technology will increase the number of antennas exponentially, and the number of channels may reach 64 or even 128, and each antenna needs to be equipped with a corresponding duplexer. And the signal frequency selection and processing are carried out by the corresponding filter, so the demand for the filter will increase greatly; at the same time, the highly integrated and miniaturized development of the 5G base station puts forward higher requirements for the size and heat generation performance of the filter . Microwave dielectric waveguide filters, especially microwave dielectric waveguide resonator filters, have become the mainstream of m...
