Abstract

The invention discloses a phase shifter. The phase shifter comprises a body and at least one grounding piece, wherein the at least one grounding piece is arranged on a first outer surface of the body, the at least one grounding piece and the body are conducted in radio frequency and are not conducted in direct current, and at least one feeding cable is arranged on the grounding piece. The phase shift according to the embodiment of the invention has the advantages of more stable electrical properties such as standing wave and isolation and better consistency, an electromagnetic wave is prevented from being leaked, and passive intermodulation generated by contact between metal and metal is prevented.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a phase shifter. Background technique [0002] In the related art, the phase shifter has the defects of electromagnetic wave leakage, unstable electrical performance indicators such as standing waves and isolation, poor consistency, and large passive intermodulation. Contents of the invention [0003] This application is based on the inventor's discovery and recognition of the following facts and problems: [0004] In the related art, a mounting hole is provided on the side of the body of the phase shifter, and a grounding member is provided at the mounting hole, and the grounding member is sealed and fixedly connected to the side of the body of the phase shifter. The grounding piece is connected with the outer conductor of the feeder cable, so as to realize the common ground of the main body, the grounding piece and the feeder cable. [0005] The grounding element needs to...
