This part of IEC 61169, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for RF coaxial connectors with push-on coupling, typically for use in 50 © RF cables or micro-strips in microwave, telecommunication, wireless systems, and other fields (SMP3) It prescribes mating face dimensions for general purpose 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 series SMP3 RF connectors. This specification indicates 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. The SMP3 push-on coupling structure series R.F. coaxial connector with the characteristic of normative impedance 50 © are used with various kinds of RF cables or micro-strips in microwave, telecommunication, wireless systems, and other fields. The operating frequency limit is up to 65 GHz. NOTE imperial dimension are original dimensions. All undimensioned pictorial configurations are for reference purpose only.
