Abstract

The invention relates to a multi-band combiner with a cavity, which relates to the field of electronic communication and aims to solve the technical problems that ports of the conventional multi-band combiner are limited by positions and cannot be arranged optionally and the conventional multi-band combiner is large in size, high in cost and inconvenient in mounting and transport and the like. The multi-band combiner comprises a circuit with multiple ports, the circuit is formed by at least a public output port (1) and two input channels of a first input port (10) and a second input port (11) , each input channel comprises an input port and a filter, an output port of the filter is connected with the public output port (1), the filters and the output ports of the filters are connected with the public output end (1) through port coupling wires (24), and the input ports and the public input port (1) can be arranged at any positions of the outer wall of a cylindrical cavity (20). The multi-band combiner with the cavity is applicable to outdoor places crowded with people, vehicle-mounted radio stations and the communication network.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a multi-band combiner used in places with dense crowds outdoors, on-board radio stations and communication networks of locomotives, and the like. Background technique [0002] A combiner, also known as a multiplexer, refers to a device that uses an antenna to enable several transmitters or several receivers to work simultaneously without affecting each other. The multi-band combiner is used in the locomotive on-board radio, and it is also an important part of the on-board system. It is mainly used as a bridge connecting the signal source and the distribution system, and is used in multi-network system access. It realizes multi-band, multi-band The signal combination function avoids the separate construction of the distribution system in the same place, and is an effective means to realize the signal compatible coverage of the multi-band network, and can effectively ensure...
