Abstract
A multiplexer includes a dielectric base plate, a connection structure, and a plurality of bandpass filters with different operation frequencies. A conductive thin film layer is disposed on a side plane of the dielectric base plate, and includes a signal wire and one or more grounding plates on a side of the signal wire. The connection structure is disposed on the conductive thin film layer, and includes a main branch and a plurality of branches, where the main branch is connected to the plurality of branches respectively, and serves as an input port of the multiplexer. Each of the plurality of bandpass filters is connected to the signal wire and the one or more grounding plates. The bandpass filter includes a first port and a second port, the first port is connected to a corresponding branch, and the second port serves as one of output ports of the multiplexer.
