This part of IEC 61169 is a framework specification. It contains information and rules for the preparation of design specifications for threaded RF coaxial connectors type SC with 50 O characteristic impedance. The connectors are used with flexible and semi-rigid cables. It is recommended to use them in medium power and low reflection applications up to 11 GHz. The dielectrically filled interface is particularly advantageous in applications with high environmental impact.
It specifies for general connectors - Class 2 and standard test connectors - Class 0 mating face dimensions, dimensional data, measurement information as well as test plans and test requirements selected from IEC 61169-1 and applicable to all type specifications for SC-type RF connectors. The SC type interface specified in this specification is equivalent to the SC-B type interface in IEC 60169-21: 1985.
This specification indicates recommended performance characteristics to be considered when preparing a type specification and includes test plans and inspection requirements for evaluation levels M and H.
The standard thus offers investment security for manufacturers and users and provides test laboratories and manufacturers with defined information on testing.
