Abstract

The application provides a dielectric waveguide duplexer. The dielectric waveguide duplexer is composed of at least two dielectric resonators; the dielectric resonator is provided with a metallized blind hole and an air through hole; the metallized blind hole is opened On the top of the dielectric resonator, the surface of the metallized blind hole is coated with a metal layer; the bottom of the metallized blind hole is provided with an air through hole, and the air through hole penetrates the bottom of the dielectric resonator, and the air through hole can be filled with metal material ; A metallized through hole is provided on the common port between the two dielectric resonators, the surface of the metallized through hole is plated with a metal layer, and a joint is connected above the metallized through hole. This application solves the problem that the existing dielectric waveguide duplexer is irreversible in the way of delay adjustment through the short circuit of the metallized through hole. Once the plated metallized through hole is opened, the dielectric resonator on this side can no longer restore the original state. , leading to the technical problem that the performance of the duplexer in radio frequency signal transmission is affected.

Description

technical field

[0001] The present application relates to the technical field of microwave communication, in particular to a dielectric waveguide duplexer. Background technique

[0002] Duplexer, generally a relatively special two-way three-terminal filter composed of two filters, is the main accessory of different frequency duplex radio stations, repeaters, etc., and its function is to isolate the transmission and reception signals to ensure reception and launch both work fine at the same time.

[0003] The existing duplexers include dielectric waveguide duplexers and metal cavity duplexers, etc. Compared with metal cavity duplexers, the size and weight of the product can be greatly reduced, so it will gradually become a part of the future development of duplexers. a trend.

[0004] In the actual debugging process of the dielectric waveguide duplexer, it is necessary to adjust the time delay of the two opposite ports of the duplexer, which is different from the traditiona...
