Description

technical field [0001] The invention relates to a microwave integrated switch system, in particular to a radiation harmonic test system with a microwave integrated switch and a switching method. Background technique [0002] At present, in the radio frequency performance test of mobile phones, more and more attention is paid to the test of the radiation performance of the whole machine, which reflects the final transmission and reception performance of the mobile phone. At present, there are mainly two methods to investigate the radiation performance of mobile phones: one is to judge from the radiation performance of the antenna, which is a relatively traditional antenna test method, called passive test; the other is to use it in a specific microwave anechoic chamber. Testing the radiation power and receiving sensitivity of mobile phones is called active testing. The OTA (Over The Air) test belongs to the active test, but at present, when the microwave switch in the radiati...

AI Technical Summary

Problems solved by technology

The OTA (Over The Air) test is an active test, but at present, when the microwave switch in the radiation harmonic test system selects the switch in the frequency band, the communication antenna needs to be connected manually, and both frequency band switching and polarization switching are required. Manually operate the switch to complete, resulting in more troublesome operation, and in the prior art, the radiation harmonic test system is compatible with the antenna OTA test system, resulting in more cables connected to the existing test equipment, and it is necessary to manually switch the test mode, which will eventually lead to It is troublesome to switch and disassemble the compatible test system. Every disassembly and assembly will bring system errors. Therefore, how to design a solution to bring convenience to polarization switching and frequency band selection switching during the use test process, and reduce the disassembly of the compatible system. The system test error problem generated by the installation is particularly important
