RF interference

ARC Technologies LLC, a Hexcel Company, has developed a reputation for providing an unrivaled range of advanced materials that help military platforms operate and survive in a high-end threat environment.

When traditional EMC troubleshooting tools fall short, the reciprocity theorem can reveal hidden immunity problems. This real‑world case study shows how unexpected RF sources—like walkie‑talkies—can expose susceptibility paths, helping engineers diagnose failures and strengthen designs with simple, effective fixes.

Audio rectification is a common EMI problem in which high-frequency RF signals interfere with low-frequency audio circuits, producing audible noise or distortion. This article explains the causes of audio rectification, demonstrates TDMA/GSM effects on speakers, and offers practical EMI mitigation techniques for designers.

As connected devices multiply and wireless networks grow denser, EMC engineers face a landscape that keeps expanding in scope and complexity. This piece examines how IoT, 5G, and Machine-to-Machine communications are reshaping the practice of EMC — and what compliance professionals need to understand to keep pace.
