Overview
IEC 61169-53:2015 is an international standard published by the International Electrotechnical Commission (IEC) that specifies requirements for radio-frequency (RF) coaxial connectors with a 16 mm inner diameter outer conductor, featuring screw lock mechanisms and a characteristic impedance of 50 Ohms. Known by the designation Type S7-16, these connectors are primarily utilized in 50 Ohm cable networks for high-performance RF and microwave transmission systems. This sectional specification provides detailed guidance for the preparation of detail specifications (DS), encompassing dimensional, performance, and testing parameters for these RF coaxial connectors.
