Problems solved by technology
And because the voltage of the signal after resonating in the resonant cavity is many times that of the strip transmission line, it is more easily affected by the processing surface, electroplating and assembly of the product
It is easy to produce unqualified batches of third-order intermodulation, so the existing technology still needs to be improved

The invention discloses a mobile 4G combiner dedicated to China mobile and relates to the technical field of combiners. The mobile 4G combiner comprises a cavity in which a TDF&TDA radiofrequency access, a TDE radiofrequency access, and a GSM&DCS radiofrequency access are arranged. The GSM&DCS radiofrequency access is formed by a GSM&DCS port, coupling sheets, a cavity band-stop filter, a strip line band-stop filter, and an ANT antenna interface. The coupling sheets are arranged in the cavity band-stop filter and the strip line band-stop filter. One end of each coupling sheet is electrically connected with the GSM&DCS port. The other end of the GSM&DCS port is a common tap. The common tap is electrically connected with the ANT antenna interface. The cavity band-stop filter comprises a plurality of resonant cavities in which resonant columns are arranged. The coupling sheets are provided with coupling ends extending into the resonant cavities. Gaps are arranged between the coupling ends and the resonant columns. The strip line band-stop filter comprises multiple strip line isolating chambers side by side. The coupling ends of the coupling sheets extend into the strip line isolating chambers. The mobile 4G combiner has beneficial effects of solving a problem of a low intermodulation qualified rate of China mobile 4G combiner in the prior art, increasing product production efficiency, and reducing production cost.
Description
【Technical field】 [0001] The invention relates to a combiner in the field of mobile communication, more specifically, the invention relates to a mobile 4G combiner dedicated to China Mobile. 【Background technique】 [0002] In 4G network construction, indoor distribution is an important part of it. The signal coverage in the building needs to combine 2G, 3G and 4G signals into the same wired network for transmission. Using a combiner can save feeder cables and simplify the system. And the purpose of reducing costs, so the combiner is an indispensable part of indoor distribution. In the realization of the combiner, the third-order intermodulation is the most difficult to meet in its index. If the third-order intermodulation is not good, it will lead to mutual interference of the system. At present, the three-port combiner required by China Mobile is GSM&DCS / TDF&TDA / TDE (see the specification attached figure 1 ), it is more difficult to achieve its comprehensive index require...
