Description

Technical Field

[0001] The utility model relates to the field of combiners, in particular to a double-layer combiner. Background Art

[0002] The combiner is connected to the back stage of the antenna in the base station. The signal received by the antenna is filtered by the combiner and transmitted to the base station receiver. Alternatively, the signal of the transmitter is filtered and combined by the combiner, transmitted to the antenna, and emitted by the antenna.

[0003] When two combiners need to be installed, the prior art is to set up two independent combiners, which not only takes up a lot of space, but also requires multiple lines to be connected inside, which easily leads to the problem of complicated lines. Finally, the cost is increased because two independent shells need to be made. Utility Model Content

[0006] Furthermore, the upper cavity and the lower cavity have the same size.

[0007] Furthermore, the semi-steel cable is threadedly connected in the cable interface.

[0008] Furthermore, the upper cover is fixedly connected to the top of the cavity by a plurality of upper cover fixing screws.

[0009] Furthermore, the lower cover is fixedly connected to the bottom of the cavity by a plurality of lower cover fixing screws.

[0010] Furthermore, the transmission sheet is fixed in the upper cavity and the lower cavity by means of a transmission sheet support and transmission sheet fixing screws.

[0011] Furthermore, the cross-coupling sheet is fixed to the transmission sheet by coupling sheet fixing screws.

[0012] Furthermore, the cross-coupling rods are fixed on the transmission sheet by coupling rod supporting screws.

[0013] The utility model provides a double-layer combiner, which has the advantages of:

[0014] 1. The double-layer combiner described in the present application can place components in both the upper and lower cavities by dividing the cavity into an upper cavity and a lower cavity, thereby reducing the space of the combiner, saving materials and installation space, and further reducing the volume in the base station.

[0015] 2. The tuning screw is designed on the same side as the semi-steel cable, which can effectively avoid the transmission plate. The tuning screw has a large debugging space and a larger power capacity. When the debugger debugs the product, there is no need to flip it over for debugging, which effectively saves debugging time.
