SMC connector
SMC connectors are coaxial RF connectors developed in the 1960s. The interface specifications for the SMC and many other connectors are referenced in MIL-STD-348. They use a #10-32 UNF threaded interface. They offer electrical performance from DC to 10 GHz. Male SMC connectors have a socket for the center contact, and Female SMC connectors have a pin for the center contact. SMC jack connectors have an external thread while SMC plug connectors have the mating hex nut. Available in 50-Ohm and 75-Ohm characteristic impedance, they provide an interconnect means for small form factor coaxial cables and printed circuit boards where small footprint is important.
The term Subvis connector appears to be European usage; the connectors appear to be electrically and mechanically equivalent to SMC.
