Test seat of passive microwave radio frequency transformer

Abstract

The invention discloses a test seat of a passive microwave radio frequency transformer. The test seat comprises a cavity, a circuit board, a positioning board and a spring thimble clamp. An open-ended cavity of an upper end surface of the cavity is fixedly connected to a pedestal. The circuit board and the positioning board are fixedly placed in the cavity from bottom to top. The circuit board is connected to monitoring equipment through a lead. The positioning board is provided with a groove which is used for placing the transformer. The spring thimble clamp is fixedly connected to a stand column and is provided with a compression bar which can elastically recover stretching. A position of the compression bar directly faces the groove. The stand column is fixedly connected to the pedestal. In the invention, a tested device is placed in the groove so as to carry out positioning; and the compression bar which can elastically recover stretching is used to carry out fastening so that tight contact of a pin is realized. By using the test seat of the invention, problems of mechanical damages and poor contact brought by a welding mode in the prior art are solved. The test seat possesses characteristics that the structure is simple; reliability and maneuverability are high; loading and unloading are convenient; test efficiency is high; the device has no loss and so on. And the test seat is suitable for a test of a large quantity of products.

Description

technical field [0001] The invention belongs to the technical field of microwave radio frequency transformer testing equipment, and relates to a test seat of a passive microwave radio frequency transformer. Background technique [0002] Passive microwave RF transformer, which works at 1.71GHz to 1.91GHz, due to its special package and small size of the microwave device, the method of directly welding the test line to the device is usually used for testing, and the welding cannot be completed when the size is small and It is especially easy to short-circuit. This test method has serious shortcomings. The properties of the device itself are destroyed during the welding process, and it is time-consuming and labor-intensive. The test process is prone to errors, and the device test cannot be easily completed at all. There is no corresponding fixture at present. carry out testing. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
