Overview
IEC 61169-10:2024 is an International Electrotechnical Commission (IEC) standard specifying the sectional requirements for RF coaxial connectors, specifically series SMB connectors with a snap-on coupling mechanism. These connectors possess an inner diameter of 3 mm in the outer conductor and a characteristic impedance of 50 Ω. This standard focuses on ensuring interoperability, consistent performance, and quality assurance in RF systems operating at frequencies up to 4 GHz.
The document provides detailed guidance for preparing detail specifications, including dimensional parameters, quality assessment procedures, and recommended tests. It serves as a foundation for manufacturers and engineers to develop or select SMB connectors that meet global performance and interchangeability criteria for microwave transmission systems.
