Abstract:

This paper presents a kind of differential-mode current injection testing technology.The equal response voltage on the equipment port was regarded as equivalent principle.The injection and radiation response analysis model and the injection voltage source extrapolation model were established.The conditions of using injection as a substitute for radiation were determined.Moreover,this paper discussed the implementation technology of differential-mode current injection.The function and structure design scheme of the auxiliary test equipment was proposed.The equivalent relation between injected voltage and radiated field was derived.On the basis of the above,the differential-mode current injection test method was summarized.Finally,the test results of typical RF front-end system verify the validity of the proposed method.

Key words: HIRF, differential-mode current injection, linear extrapolation, directional coupling device, equivalent source wave
