SMA series RF coaxial connectors appeared in the 1960s. With a threaded connection structure, suitable for radio equipment and electronic equipment in the RF circuit, connecting RF cable, semi-soft, semi-steel RF cable. The maximum available frequency is limited by the type of coaxial cable to which it is connected. The application of microwave applications is mainly reflected in the conversion from coaxial cable to waveguide, and the conversion of printed circuit board signs of microwave transmission. I produced the SMA series of products are in line with GJB681 (MIL-C-39012) specification. But individual product specifications will also change within the specified range.
