SMA cables, SMA being 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 on SMA Cables feature screw-type coupling. Semi-Rigid SMA cables extend the frequency range of the device to 18GHz. SMA cables offer broadband performance with low reflections and constant 50 ohm impedance. These properties, along with minimum attenuation and low VSWR have made the SMA cable extremely popular in the microwave community. LTI SMA cables are designed to conform to MIL-C-39012 specifications.
