Radio-frequency connectors – Part 26: Sectional specification for TNCA series RF coaxial connectors
|Publication Date:||1 January 2013|
|ICS Code (Plug-and-socket devices. Connectors):||31.220.10|
This part of IEC 61169 which is a sectional specification (SS) provides information and rules for the preparation of detail specifications (DS) for TNCA series RF coaxial connectors, with characteristic impedance of 50 Ω, with threaded coupling and operating frequency limit up to 18 GHz, used in wireless, communication, instrument, antenna, test and measurements, radar, and other fields, connecting with RF cables or micro-strips.
It also prescribes mating face dimensions for general connectors-grade 2, dimensional details of standard test connectors-grade 0, gauging information and tests selected from IEC 61169-1, applicable to all detail specifications relating to TNCA series connectors.
This specification indicates the recommended performance characteristics to be considered when writing a detail specification and it covers test schedules and inspection requirements for assessment levels M and H.
TNCA connectors are recommended for applications above 11 GHz. TNCA connectors are compatible with TNC connectors as described in the IEC 60169-17 and IEC 60169-26 provided that the dielectric of connector with socket-centre contact does not extend beyond reference plane. However when mated with these connectors, the performances are not ensured.
NOTE Attention is drawn to the fact that TNCA interface does not utilize overlapping PTFE dielectric for increased voltage breakdown resistance.
