The SMC "SubMiniature C" connector series was designed as a smaller screw-on coupling replacement for the SMA connector. Gender designation can be confusing, with the smaller 'jack' body containing the male pin and as such the smaller connector is male, and larger connector having the female receptacle. SMC has a threaded coupling for vibration proof installation, and is usable up to 10 GHz. The connector is not as robust as the standard SMA connector, with mating cycles often limited to 100 or fewer.
