Coaxial D38999 Interconnects

Picture for category Coaxial D38999 Interconnects

SV Microwave offers a wide variety of DC to 65 GHz high frequency size 8, 12, 16, and 20 coaxial contacts for the D38999 Series III housing and standard inserts. These contacts allow any application to continue to use the D38999 connector and be able to expand the use to include the microwave transmission lines. For further versatility in the field, SV also offers SOSA-aligned Size 8 and 12 contacts, as well as fixed-length 75 Ohm RF MCX Cable Assemblies.

Features / Benefits: 

  • Superior electrical performance and high frequency capability
  • Blindmate advantage and maintenance of an accurate phase length when mated
  • Uses standard interfaces based on MIL-STD-348, and can be installed in any MIL-DTL-38999 size 8, 12, 16, or 20 insert
  • Unique “Float Mount” technology allows for consistent microwave performance while maintaining tight mechanical tolerances
  • Assemblies with interfaces modified for true 75 Ω impedance through both cable and connector available
  • SOSA™ Aligned high frequency RF contacts for D38999 available

Applications:

  • Military and Aerospace
  • Severe/Harsh Environments
  • Embedded Systems
  • 3G-SDI - high speed video applications that require superior shielding
  • Ruggedized I/O video connections for military applications
  • High definition camera links for UAV platforms
