IEC 61169-26:2013 is a sectional specification (SS), it provides information and rules for the preparation of detail specifications (DS) for TNCA series RF coaxial connectors, with characteristic impedance of 50 Ohms, 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.
