Abstract

The invention discloses a radio frequency test device and a system. In the embodiment of the invention, a radio frequency connector is adopted to receive a radiofrequency signal transmitted by a mobile terminal, and the radio frequency signal is transmitted to a first attenuator; the first attenuator transmits the radiofrequency signal to a signal transmission circuit which transmits the radiofrequency signal to a test unit; the test unit performs testing on the radio frequency parameters of the mobile terminal according to the radiofrequency signal in order to obtain the test result; an attenuator is added between the radio frequency connector and the signal transmission circuit; the application of the attenuator can buffer the characteristic of impedance change, reduces the interference on the radio frequency connector impedance by the signal transmission circuit, and enables the impedance of the radio frequency connector to be consistent with the impedance of the intelligent terminal radio frequency system as much as possible. Compared with the prior art, the radio frequency test device and system can improve the accuracy of the intelligent terminal radio frequency performance test, and thus improve the production efficiency of the intelligent terminal.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to a radio frequency testing device and system. Background technique [0002] With the development of smart terminals, more and more functions are compatible with smart terminals, which not only enriches users' lives, but also brings convenience to users. [0003] As we all know, the radio frequency performance is an important performance of the smart terminal, which is related to the quality of the radio frequency communication of the smart terminal. Therefore, in order to ensure the radio frequency performance of the smart terminal or ensure the consistency of the radio The terminal performs a radio frequency calibration test. [0004] In order to ensure the accuracy of the RF calibration test, it is necessary to keep the impedance of the connection end of the calibration test system consistent with the impedance of the RF system of the smart terminal, that is, to ensure...
