SMA connectors, short for SubMiniature Version A, are semi-precision, subminiature devices that provide repeatable electrical performance from DC to 12.4 GHz with flexible cable. SMA connectors feature screw-type coupling. Semi-Rigid cabling extends the frequency range of the device to 18GHz. SMA connectors offer broadband performance with low reflections and constant 50 ohm impedance. These properties, along with minimum attenuation and low VSWR have made the SMA connector extremely popular in the microwave community. LTI SMA connectors are designed to conform to MIL-C-39012 specifications.
