* 主要用途 : SMA
connectors are 50Ω sub-miniature coaxial connectors for
DC to 18GHz with low reflection.
Kai Dee Jin SMA connectors are precision connectors for microwave Applications up to 18GHz/26.5 GHz. They distinguish themselves through their high mechanical strength, high durability, high reliability and low VSWR.
SMA launchers are the preferred connection elements for varied microwave circuits including hermetically sealed designs. There is a huge variety of Applications for Kai Dee Jin SMA connectors, such as test + measurement, mobile communication, avionics, etc.
