The coupler comprises a cavity body, a cavity cover, an input port, an output port, a first coupling port, a first load port, a second coupling port, a second load port, a transmission conductor, a first coupling conductor and a second coupling conductor, wherein an accommodating space is formed by the cavity cover and the cavity body; the transmission conductor, the first coupling conductor and the second coupling connector are arranged in the accommodating space; the input port and the output port are formed in two opposite ends of the cavity body respectively; two ends of the transmission conductor are connected with the input port and the output port respectively; the first coupling port, the first load port, the second coupling port and the second load port are formed in the side face of the cavity body; two ends of the first coupling conductor are connected with the first coupling port and the first load port respectively; two ends of the second coupling conductor are connected with the second coupling port and the second load port respectively; the transmission conductor comprises a first transmission body parallel to the first coupling conductor and a second transmission body parallel to the second coupling conductor. The coupler can realize bidirectional coupling.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a coupler. Background technique [0002] In modern wireless communication systems, passive devices are widely used for their environmental protection, low power consumption and high reliability. Coupler is a very commonly used device in passive devices. Its main feature is that the coupling loss can be designed according to actual needs. It has the advantages of wide operating frequency, low in-band insertion loss, high isolation, and small standing wave ratio. [0003] In the prior art, couplers are required to have a bidirectional coupling function in some occasions. Although some current couplers can have a bidirectional coupling function, with the increase of signal power, bidirectional coupling in certain frequency ranges of UHF The design of the device will become very difficult, and the strength of its two-way coupling signals will also change, and it is necessary t...
