Abstract

The invention discloses a radio frequency testing device and a radio frequency testing method, and relates to the technical field of radio frequency testing equipment. The testing device comprises a testing mechanism; the testing mechanism comprises a pricking pin testing module; an upper air channel groove extending transversely is formed in the position, corresponding to a chip of a product, ofa radio frequency pin base of the pricking pin testing module, and a lower air channel groove with the extending direction consistent with the extending direction of the upper air channel groove is formed in a positioning plate located below the product; one side of the upper air channel groove and one side of the lower air channel groove are provided with a fan blowing air in the extending direction of the upper air channel groove and the lower air channel groove. A guide groove is vertically formed in the position, corresponding to the chip, of the upper air channel groove; a heat dissipation copper block making contact with the chip is arranged in the guide groove in an elastic floating mode, and a first heat dissipation groove is formed in the end, making contact with the chip, of theheat dissipation copper block. The radio frequency testing device solves the problem about how to dissipate heat and reduce temperature of a chip in the radio frequency testing process, can complete the radio frequency testing of a product at one time, guarantees the accuracy of a radio frequency testing result, and reduces the testing cost.

Description

technical field [0001] The invention relates to the technical field of radio frequency testing equipment, in particular to a radio frequency testing device and a radio frequency testing method. Background technique [0002] Radio frequency refers to the electromagnetic frequency that can radiate into space, and the frequency range is from 300KHz to 300GHz. Radio frequency is referred to as RF, and radio frequency is radio frequency current, which is an abbreviation of high-frequency alternating electromagnetic waves. [0003] The shielding box is a shielding body of various shapes such as shells, plates, and sleeves made of conductive or magnetically conductive materials, which limits the electromagnetic capability within a certain space and is used to suppress radiation interference. A device that performs processing to provide a non-interfering test environment for the wireless communication device under test. [0004] In recent years, thanks to the promotion of various ...
