High Frequency Contacts

Amphenol High Frequency Contacts
Amphenol and SV Microwave (an Amphenol company) offer DC to 40 GHz high frequency size 8, 12 and 16 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.

FEATURES & BENEFITS:

• Superior electrical performance and high frequency capability
• Blindmate advantage and maintenance of an accurate phase length when mated
• Can be terminated to a multiple of cable types depending on the application
• Uses standard interfaces based on MIL-STD-348, and can be installed in any MIL-DTL-38999 size 8, 12 or 16 insert
• Unique “Float Mount” technology allows for consistent microwave performance while maintaining tight mechanical tolerances
