Abstract

In digital circuit design, the design defect of signal integrity is also the root of EMC problem. This paper introduces the mechanism of electromagnetic compatibility problem due to circuit signal integrity problem, based on the case analysis of a project circuit jamming satellite receiver frequency band, we used the method of combining actual measurement with signal integrity and electromagnetic compatibility simulation based on Hyperlynx software, to find the causes of the problem, and the solution and design improvement suggestions are given. The experimental results show that the problem of electromagnetic radiation interference has been effectively solved.
