SMA connectors are cost-effective, semi-precision, subminiature units that provide excellent repeatable electrical performance from DC to 12.4 GHz with flexible cable. They are best suited for use with fight-frequency semi-rigid cables that extend the frequency range of the device to 18 GHz. This series of SMA connectors with characteristic impedance of 50 ohm has been designed to achieve a high level of electrical performance. These properties, minimum attenuation and low VSWR have made the SMA connectors extremely popular in the microwave community. The SMA connectors are designed for applications requiring high levels of electrical performance such as wireless communications, radars, avionics and test and measurement equipments.
