D38999 High-Frequency Coaxial Contacts

Amphenol / SV Microwave D38999 High-Frequency Coaxial Contacts feature a DC to 65GHz high-frequency rating and 8, 12, 16, and 20 contact sizes for the D38999 series II and III housing and standard inserts. The series features a unique float-mount technology that enables consistent microwave performance while maintaining tight mechanical tolerances. Amphenol / SV Microwave D38999 High-Frequency Coaxial Contacts allow applications to continually use the D38999 connector and expand the usage to microwave transmission lines. These connectors are ideal for embedded systems in military and aerospace applications and for severe or harsh environments.
