Connector >> SMA

 

Zeeteq 50 ohm SMA coaxial connectors are subminiature, precision connectors operating up to 18GHz on semi-rigid cables and 12.4GHz on flexible cables. Its threaded coupling mechanism features high durability, high reliability and low VSWR.
SMA connectors are widely used in radar, microwave communication and instrumentation.
Zeeteq’s SMA connectors comply with IEC 60169-15, they are available in two versions of body: passivated stainless steel is for high durability, the brass with gold plated is a standard usage.
