SMA connectors (SMA for SubMiniature version A) are coaxial RF connectors developed in the 1960's as a minimal connector interface for coaxial cable with a screw type coupling mechanism. It offers excellent electrical performance from DC to 18 GHz. Frequently used in mass numbers in particle accelerators, the SMA connector is used in conjunction with Heliax cable as a connector for X and Y in Particle beam diagnostics, after Quadrupole magnets. The AC feedback signal, X and Y are fed through four SMA connectors from the beam position monitor to the beam monitor instrumentation.
