FT test system and method for RF chip

Abstract

The invention relates to an FT test system of an RF chip. The FT test system comprises an MCU module, a signal source module, a TP module, a chip to be tested, a Power Detector and a DC test machine. The DC test machine is in communication connection with the MCU module and is used for transmitting a control instruction to the MCU module; and the MCU module is connected with the TP module and the signal source module, outputs a digital logic signal and a low-frequency clock signal to the TP module according to a control instruction transmitted by the DC test machine, and outputs the digital logic signal to the signal source module to control the switching of the signal source module and the frequency of the output signal. According to the invention, the FT test work of the RF chip can be carried out without using a special RF chip test machine, and a large amount of fund and time cost can be saved on the premise of ensuring the test accuracy.

Description

technical field [0001] The invention relates to the field of RF chip testing, in particular to an FT testing system and method for RF chips. Background technique [0002] The RF chip is an electronic component that converts radio signal communication into a certain radio signal waveform and sends it out through antenna resonance. Compared with general power chips, in mass-production FT testing, in addition to various OS tests on RF chips, gain testing is also required. [0003] At present, the test machine used for FT testing of RF chips usually needs an external radio frequency signal generator, and the radio frequency signal is input into the chip under test through the Cable line, and then the chip under test will also pass the frequency conversion amplified signal through the Cable Line input testing machine, by comparing the properties of the two signals before and after, you can judge whether the function of the chip is qualified. [0004] This kind of dedicated RF c...

Problems solved by technology

[0004] This kind of dedicated RF chip testing machine is expensive (generally tens of millions or even hundreds of millions of RMB) and the quantity is scarce, entrusting packaging and testing manufacturers to test costs is high, and when the chip test is busy, the use of the machine will be relatively tight. If the test is queued, it is easy to cause delays in delivery, which will greatly increase the capital and time costs of IC design companies
