Combiner

Abstract

The invention provides a combiner, which comprises a cavity body with a cavity and a cover plate, wherein two ends of the cavity body are respectively provided with connecting ports, and the cavity body is internally provided with a partition plates for separating the cavity into a high-pass filtering cavity and a low-pass filtering cavity; the high-pass filtering cavity is internally provided with a conductor assembly with two ends being respectively and correspondingly electrically connected with the connecting ports at two ends of the cavity body, the conductor assembly includes a pluralityof conductors, and the plurality of conductors are arranged along the longitudinal direction of the cavity and are sequentially in capacitive coupling connection; and the low-pass filtering cavity isinternally provided with a strip line filtering path with two ends being respectively and correspondingly electrically connected with connecting ports for input and output. The combiner provided by the invention integrates a low-pass path and a high-pass path, can be applied to a 5G high frequency band and achieves the advantages of high Q-value, high power capacity, wide pass band, high isolation and the like.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a combiner. Background technique [0002] Cavity filters and cavity combiners are widely used in the field of modern communications. The basic functions are: to allow useful signals to pass through the signal link to the maximum extent, and to suppress useless signals to the maximum extent. At the same time, the combiner can also Split and combine signals in different frequency bands. With the rapid advancement of 5G technology, in order to obtain larger channel capacity and higher transmission rate, mobile communication systems are developing towards higher frequencies. In order to achieve coexistence with existing systems, the combiner is required to meet wider bandwidth requirements. In this way, during the evolution of the mobile communication system, a high-performance combiner is naturally required. [0003] The combiner in the prior art is mainly implemented by combi...

AI Technical Summary

Problems solved by technology

Its advantages are high Q value and large power capacity, and the poles can be increased by cross-coupling to meet the requirements of strong out-of-band suppression. bandwidth

Such a combiner cannot meet the requirements of high isolation, high power, and bandwidth between mobile communication systems, and a better combining solution must be found
