Abstract

The invention relates to a radio frequency compensator, a radio frequency test method and a radio frequency test system, the radio frequency compensator is applied to the radio frequency test system,the test system comprises a test device and a device to be tested, the radio frequency compensator comprises a plurality of impedance matching networks, and the impedance values of the impedance matching networks are different, wherein the radio frequency compensator is used for being connected with the test equipment and the equipment to be tested in series to form a test link in the radio frequency test system, and the radio frequency compensator is connected with the test equipment and the equipment to be tested in series in the test process of the equipment to be tested. The test equipmentis selectively and electrically communicated with the equipment to be tested through any one impedance matching network in the plurality of impedance matching networks, so that the sum of the impedance value of the radio frequency compensator and the impedance value of the equipment to be tested is matched with the impedance value of the test equipment.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a radio frequency compensator, a radio frequency test method and a system. Background technique [0002] During the manufacturing process of many electronic products, relevant electrical performance tests are carried out on the products. Among them, radio frequency test is a very important test link. [0003] The radio frequency test method adopted in the related art is more dependent on the relevant characteristics of the test fixture and the test wire, but under the influence of some factors, the relevant test tools are prone to produce corresponding characteristic deviations, which eventually leads to a decrease in test accuracy. Contents of the invention [0004] The purpose of the present disclosure is to provide a radio frequency compensator, a radio frequency test method and system to solve the above technical problems. [0005] In order to achieve...
