SMC Connectors
SMC (SubMiniature version C) connectors are coaxial RF connectors developed in the 1960s. They use a #10-32 UNF threaded interface (screw type). They offer excellent electrical performance from DC to 10 GHz. Female SMC connectors have a pin for the center contact, and male SMC connectors have a socket for the center contact, and are therefore analogous to the "reverse polarity" versions of other types of RF connectors
