Phase shifter

Abstract

The present disclosure provides a phase shifter including a circuit board, a substrate, and a plurality of cables. Each of the plurality of cables includes a first insulation layer, an outer conductive layer and an inner conductive layer. The outer conductive layer is inserted into the first insulation layer. The outer conductive layer and the inner conductive layer are disposed at intervals. The circuit board is electrically connected to the inner conductive layer of each of the plurality of cables. The substrate includes a plurality of casings for grounding, and the circuit board is disposed on the substrate. Each of the plurality of cables passes through at least one of the plurality of casings. The first insulation layer of each of the plurality of cables is located between the outer conductive layer and the corresponding casing, and forms electrical coupling between the outer conductive layer and the corresponding casing. The present disclosure solves the problem that the connection between the outer conductive layer of the cable and the printed circuit board in the present phase shifter is complicated.
