RF Microwave Coaxial SMA Connector are high performance subminiature connectors for microwave frequencies. The threaded coupling insures uniform contact of the outer conductors, which enables the SMA to minimize reflections and attenuation at higher frequencies while providing a high degree of mechanical strength and durability.

Typical applications for SMA connectors include microwave active and passive components, instrumentation, avionics, and other high-end radio electronics.

Note :Reverse Polarity Connectors are available on special order.
