  • Feature a .145 maximum overall diameter with a 0.375 overall length for the mated connector pair
  • 50 ohm characteristic impedance maintained throughout the mated connector pair
  • VSWR (1.25:1) from DC to 20 GHz.
  • High frequency RF applications from DC to 20 GHz.

The SCX series offers the utmost savings in space utilization without compromising rugged mechanical performance and superior RF high frequency electrical performance. SCX connectors feature a .145” maximum overall diameter with a .375” overall length for the mated connector pair. A revolutionary designed air dielectric interface resulting in exceptional RF performance with a 50-ohm characteristic impedance maintained throughout the mated connector pair. The result is an extremely small and rugged high frequency RF connector series with exceptionally low VSWR (1.25:1) from DC to 20 GHz. 

Additional Features: 

  • Low VSWR (1.25:1) from DC to 20 GHz
  • Min 1,000 mating cycles without degradation
  • 50 Ohm characteristic impedance
  • Surface mount, end launch, compliant pin, press fit and PCB mounting alternatives available
