Radio-frequency connectors – Part 14: R.F. coaxial connectors with inner diameter of outer conductor 12 mm with screw coupling – Characteristic impedance 75 ohms (Type 3,5/12)
|Publication Date:||1 October 2010|
|ICS Code (RF connectors):||33.120.30|
This standard concerns RF coaxial connectors for use with RF cables both flexible and semirigid, where air dielectric interface and high mechanical stability is required for severe environmental exposure. The connectors provide low reflection in the microwave region up to 12 GHz and all patterns may provide sealing up to a pressure differential of 3 bar.
For this type of connector, cables IEC 75-7-and 75-8 of IEC 61196-6: Coaxial communication cables - Part 6: Sectional specification for CATV drop cables, are recommended.
This type is known commercially as the 3,5/12 connector.
