Abstract

The invention relates to the technical field of microwave device testing devices, in particular to an orthogonal mode coupler (OMT) testing tool. The testing tool comprises an upper module and a lower module, the upper module comprises an upper mold core, a guide ring, a 90 DEG rotation stop block, an upper mold pull rod and two linear bearings, four second fixing holes are symmetrically formed in the center of the guide ring, the guide ring penetrates through the corresponding second fixing holes through bolts to be fixedly connected with the bottom of the upper die core, a square hole is formed in the center of the 90 DEG rotation stop block, the 90 DEG rotation stop block is slidably connected with the upper die core through the square hole, and four first fixing holes are symmetrically formed in the center of the 90 DEG rotation stop block. When the waveguide transmission port is butted in the S parameter test, screw locking is not needed, the damage probability of the DUT caused by screw locking is avoided, meanwhile, the test time is greatly shortened, the efficiency is improved, and the purpose of reducing the test cost is achieved.

Description

technical field

[0001] The invention relates to the technical field of microwave device testing devices, in particular to an orthogonal mode coupler (OMT) testing tool. Background technique

[0002] In a microwave system, it is often necessary to divide one microwave power into several circuits in proportion. This is the problem of power distribution. The components that realize this function are called power distribution components or couplers, which mainly include directional couplers, power dividers and various components. A microwave branch device, a photoelectric coupler is an electric-optical-electric conversion device that transmits electrical signals through light as a medium. It consists of two parts: a light source and a light receiver. In the body, they are isolated from each other by a transparent insulator. The pin of the light source is the input end, and the pin of the light receiver is the output end. The common light source is a light-emitting diode, and the...
