Abstract

The embodiment of the invention discloses a multi-frequency combiner, which comprises a transmitting combiner and a receiving combiner which respectively comprise a first wave filter and a second wave filter, an input / output port of each first wave filter is connected with a resonator in a head / tail cavity of the first wave filter through a one quarter wavelength tapping wire, an input / output port of each second wave filter is connected with a resonator in a head / tail cavity of the second wave filter through a one quarter wavelength tapping wire, input ports of the first wave filter and the second wave filter are connected through a one quarter wavelength wire, and output ports of the first wave filter and the second wave filter are connected through a one quarter wavelength wire; a single cross coupling window is arranged between the head cavities of the first wave filter and the second wave filter, and a single cross coupling window is arranged between the tail cavities of the first wave filter and the second wave filter. The multi-frequency combiner provided by the invention realizes non-interference between receiving and transmitting signals, and is easy to debug, and the processing cost is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular to a multi-frequency combiner. Background technique [0002] In the application of mobile communication base station system, in order to achieve the purpose of simplifying system design, the receiving / transmitting ends of two sets of base stations usually share a set of antenna end to realize the function of receiving or transmitting signals. The receiving and transmitting signals do not interfere with each other. The prior art mobile communication base station system uses a signal combiner which is combined with a 3dB bridge and a band-pass filter. [0003] See figure 1 , figure 1 is an equivalent circuit diagram of a signal combiner in the prior art. Such as figure 1 As shown, the signal combiner 10 in the prior art includes: a first base station BTS1 (Base Transceiver Station), a second base station BTS2, a first 3dB bridge 101, a first...
