Radio frequency performance test device

Abstract

The invention discloses a radio frequency performance test device comprising a shielding box, an antenna and a clamp. The shielding box comprises a shielding cavity which is internally provided with a fixing plate. The antenna is fixedly connected on the fixing plate. The length direction of the antenna is perpendicular to the fixing plate. The clamp comprises a support and a tray. The support is slidably connected on the fixing plate along a direction close to or away from the antenna. The tray is slidably connected on the support. The sliding direction of the tray is perpendicular to the fixing plate. The tray is used for installing terminal equipment. The antenna transmits a radio frequency signal to the terminal equipment. According to the radio frequency performance test device, the position of the terminal equipment relative to the antenna is rapidly and accurately adjusted by arrangement of the clamp capable of adjusting the position of the terminal equipment so that signal transmission is facilitated, and radio frequency performance test efficiency and test result accuracy can be enhanced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a radio frequency performance testing device. Background technique [0002] In the production process of the wireless terminal, in order to ensure the production quality of the product, it is often necessary to conduct an antenna coupling test, and then determine whether the antenna in the wireless terminal meets the performance requirements through the test. [0003] At present, the existing test methods mainly include the following two types: the first one is to use a coupling triangular cone shielding box to test the radio frequency performance of the antenna of the terminal by using signaling test equipment. UniversalSerialBus (USB) cable inlet can only be connected to the USB cable after modification, but the above method will reduce the shielding performance, thereby affecting the test results, and because the terminal position is fixed, it is not convenient to check th...

Problems solved by technology

[0003] At present, the existing test methods mainly include the following two types: the first one is to use a coupling triangular cone shielding box to test the radio frequency performance of the antenna of the terminal by using signaling test equipment. UniversalSerialBus (USB) cable inlet can only be connected to the USB cable after modification, but the above method will reduce the shielding performance, thereby affecting the test results, and because the terminal position is fixed, it is not convenient to check the position of the tested object when testing in different frequency bands. Flexible adjustment

The second is to use a shielding box with a flat-panel antenna. For mobile phones with multiple antennas, it is difficult to adjust the placement of the device so that the accuracy of the test results is not high.
