SMA connector Features & Benefits
  Broadband performance DC to 18 GHz with low reflection stainless steel construction and ? - 36 threaded coupling offers high performance in a compact design.
  Low cost Commercial Grade (Brass SMA) available in nickel or gold plating which provides approximately 30% cost reduction with 250 mating cycles.
  Available for .085" and .141" diameter semi-rigid cables and all the standard flexible cables including double shielded RG-316.
  Phase Adjustable SMA connectors provide ease of mechanical screw adjustments, compared to the delays and expense of laborious cable-trimming.

 

SMA connector Applications
  Base Stations   Cable Assemblies   Components
  Instrumentation   Mil/Aero   PC/LAN
