IEC 61169-15 pdf – Radio-frequency connectors – Part 15: Sectional specification – RF coaxial connectors with inner diameter of outer conductor 4,13 mm (0,163 in) with threaded coupling – Characteristic impedance 50 Ω (type SMA)
This part of lEC 61169,which is a sectional specification (SS), provides information and rules
for the preparation of detail specifications (Ds) for RF coaxial connectors with inner diameterof outer conductor 4,13 mm (0,163 in) with threaded coupling with a characteristic impedanceof 50 (type SMA).
This document specifies mating face dimensions for high performance connectors – grade 1,dimensional details of standard test connectors – grade 0, gauging information and testsselected from IEC 61169-1, applicable to all detail specifications relating to series SMA RFconnectors.
This document indicates recommended performance characteristics to be considered whenwriting a detail specification and it covers test schedules and inspection requirements forassessment levels M and H.
The SMA types RF coaxial connectors are used with all kinds of RF cables and microstrips inmicrowave transmission systems.The operating frequency is up to 18 GHz.These connectorscan be intermated with 3,5 mm (IEEE 287-2007) and 2,92 mm (IEC 61169-35) connectors.
