The invention discloses a multi-frequency combiner, comprising a cavity, an upper cover board, a lower cover board, an upper bottom plate, a lower bottom plate and a plurality of syntony poles. A first signal input port, a second signal input port, a third signal input port, a fourth signal input port and an output port respectively arranged on the cavity; a first channel, a second channel, a third channel and a fourth channel are arranged on the cavity, the first channel, the second channel and the third channel are arranged above the cavity and are provided with upward openings, the fourth channel is arranged below the cavity and is provided with an downward opening, and the third channel and the fourth channel are arranged in a back to back way. In the invention, market demands for communication can be met, the structure is simple, the error is little, the manufacturing efficiency is high and the cost is low.
Description
Technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-frequency combining device. Background technique [0002] In the communication system, the combiner is mainly used to combine multi-system signals into an indoor distribution system. For example, in engineering applications, two frequencies of 800MHZ C network and 900MHz G network need to be combined for output. Using the above combiner, a set of indoor distribution system can work in CDMA frequency band and GSM frequency band at the same time. For another example, in a radio antenna system, after the input and output signals of several different frequency bands (such as 145MHZ and 435MHZ) are combined through the combiner, a feeder line is used to connect to the radio station. This not only saves a feeder line, but also avoids The trouble of switching between different antennas. [0003] Reference figure 1 The schematic diagram shown in the prior art is a thre...
