Multiport Connectors

SV Microwave is proud to offer size 8, 12 and 16 coaxial contacts for the D38999 housing and standard inserts, as well as for ARINC and Micro-D styles. Size 8 contacts are available in DC to 40 GHz versions, size 12 are available from DC to 60 GHz and size 16 are available from DC to 65 GHz.

High frequencies are achieved through our unique "Float Mount" technology designed into the contacts. This technology allows for consistent microwave performance while maintaining tight mechanical tolerances. These contacts exhibit superior electrical performance and, unlike other blindmate connectors, will maintain an accurate phase length when mated.

Termination types range from board mounting to semi-rigid and flexible cable. Designs are available to fit standard MIL-C-17 RG cables including .141" and .085" semi-rigid cables as well as a variety of custom and low loss flexible cables.

These contacts also use standard interfaces that are based on MIL-STD-348 and can be used with any D38999 insert. This allows your application the ability to continue to use the D38999 connector while expanding the use to include microwave transmission lines. No custom connectors or separate RF interfaces are needed.

Coordination between Amphenol divisions has produced high frequency contacts for a number of proprietary designs as well. SV and Amphenol Aerospace have collaborated to introduce high frequency contacts into their HDB3 and LRM connectors, the Amphenol Backplane Systems’ VIPER series and Amphenol Air LB’s SIM Modular Interconnection . We also produce custom multiport blocks with standard cavity sizes and SV proprietary designs.

These new contacts have enabled SV to combine RF-Microwave and D/C signal and power in hybrid harnesses. Our hybrid harnesses provide simplified interconnection and smaller package size to aid both designers and operators in the field.
