SMA plug connecters are used mainly for applications in the frequency ranges 1 GHz to 18/26.5 GHz (depending upon the design). The plug connectors are considered as male and the socket as female, depending upon the design of the inner conductor. They have a high mechanical strength owing to the screw lock (8 mm). https://elecena.pl/product/27762398/bkl-409069-sma-plug-for-crimping-50-ohm-cable-coupling-gold-plated 2025-01-26 https://elecena.pl/product/27762398/bkl-409069-sma-plug-for-crimping-50-ohm-cable-coupling-gold-plated 2025-07-25
