Abstract

The embodiments of the present invention disclose a microwave combiner. The microwave combiner is used for a new radio frequency front-end subsystem. Compared with the prior art, the microwave combiner can assist in reducing filters and 3dB combiners and improving integration. The microwave combiner includes a first common cavity, a second common cavity, a third common cavity, a first impedance converter and a second impedance converter; the first interface of the first common cavity is connected with a first signal input interface; the second interface of the first common cavity is connectedwith a first antenna interface; the third interface of the first common cavity is connected with one end of the first impedance converter; the first interface of the second common cavity is connectedwith the other end of the first impedance converter; the second interface of the second common cavity is connected with a signal output interface; the third interface of the second common cavity is connected with one end of the second impedance converter; the first interface of the third common cavity is connected with the other end of the second impedance converter; the second interface of the third common cavity is connected with a second antenna interface; and the third interface of the third common cavity is connected with a second signal input interface.

Description

technical field [0001] The present application relates to the field of microwave filter combining, in particular to a microwave combiner. Background technique [0002] With the increasing demand for base station miniaturization, the filter, as a key component in the base station module, needs to further increase the integration level. [0003] With the rapid development of the filter industry, the requirements for filter indicators are also constantly increasing. This is mainly reflected in the fact that multi-channel products share one antenna interface, high out-of-band rejection and good in-band insertion loss. small volume. In the existing technology, such as figure 1 As shown, the existing combining schemes generally use 3dB bridges for combining circuits, but when using 3dB bridges for co-frequency combining, the isolation is low, there is at least 3dB loss, and the constituted system is complex and the integration level is not high. .
