IEC 61169-44:2012 is a sectional specification (SS), it provides information and rules for preparation of detail specification of SMP series push-on RF coaxial connectors together with the pro-forma blank detail specification. The SMP push-on series connectors with characteristic impedance of 50 O are used with RF cables or micro-strips in microwave, telecommunication, wireless and other fields. The operating frequency limit is up to 40 GHz. It also prescribes mating face dimensions for general purpose connectors grade 1, dimensional details of standard test connectors grade 0, gauging information and tests selected from IEC 61169-1, applicable to all detail specifications relating to series SMP RF 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. This International Standard cancels and replaces IEC/PAS 61169-44, published in 2010.
