IEC 61196-9-1:2023

Overview

IEC 61196-9-1:2023 is an international standard published by the International Electrotechnical Commission (IEC) that provides a blank detail specification template for flexible RF coaxial communication cables. It applies specifically to flexible coaxial cables featuring solid or semi-air-spaced dielectrics combined with wrap and/or braid outer conductors. These cables are central to modern communication infrastructures and are widely deployed in mobile communication systems, microwave test equipment, consumer electronics, and related fields.

This standard serves as a foundational guideline for manufacturers, users, and national organizations to develop tailored detail specifications (DS) by filling in required cable characteristics, ensuring consistency and compliance in cable design, testing, and quality control.

Key Topics
