This sectional specification (SS) provides information and rules for the preparation of detail specifications (DS) for miniature snap-on interfaces for use with both flexible and semi-rigid coaxial cables (Series MMCX). The connectors are usable to a frequency of at least 6 GHz. It prescribes mating-face dimensions for general purpose connectors, dimensional details for standard test connectors, Grade 0, together with gauging information and the mandatory tests, selected from CECC 22 000, applicable to all DSs relating to Series MMCX connectors. This specification indicates the recommended performance characteristics to be considered when writing a DS, and covers test schedules and inspection requirements for Assessment Level H.
