Abstract

The invention discloses communication equipment and a coupler thereof. The coupler comprises a PCB, a coupling sheet and a metal cover, the coupling sheet is arranged on a first surface of the PCB, a second surface of the PCB is provided with a first groove, the projection of the coupling sheet on the PCB is partially overlapped with the first groove, and the metal cover is arranged on the first groove. The first groove is formed in the PCB, and the projection of the coupling sheet on the PCB is partially overlapped with the first groove, so that the structure of the coupler is changed, and the directivity of the coupler is improved.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a communication device and a coupler thereof. Background technique [0002] In mobile communication devices, it is necessary to use a coupler to couple the radio frequency signal in the main circuit with a certain degree of coupling, so as to realize the observation or test of the radio frequency signal. One measure of a coupler's ability to discriminate between incident and reflected waves in a transmitting system is the coupler's directivity, which affects the measurement accuracy of RF power, VSWR, and return loss. However, limited by the structure of the coupler itself, there is a certain limit to the directional parameters of the coupler. In the prior art, an adjustable coupling mechanism is added to the coupler to change the electric field between the coupler and the main circuit to change the directionality of the coupler, but it may cause insertion loss o...
