IEC/PAS 61169-44:2010(E) provides information and rules for preparation of detail specification of SMP series blind mating RF connectors together with the pro forma blank detail specification. It also prescribes mating face dimensions for general 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 RBMA series blind mating RF connectors. It 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. SMP series push-on connectors with characteristic impedance 50 ohm are used with RF cables or micro-strips in microwave, telecommunication, wireless and other fields. The operating frequency limit is up to 40 GHz.
