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 inner diameter of outer conductor 4,13 mm(0,163in) with threaded coupling with a characteristic impedance of 50©(type SMA). This document prescribes mating face dimensions for high performance 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 SMA 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 SMA types RF coaxial connectors which are used with all kinds of RF cables and microstrips in microwave transmission systems. The operating frequency is up to 18 GHz. These connectors can be intermated with 3,5mm (IEEE 287-2007) and 2,92mm (IEC 61169-35) connectors. NOTE Metric dimension are original dimensions. All undimensioned pictorial configurations are for reference purpose only.
