RF, Microwave and Datalink Contacts
for MIL-DTL-38999, SuperNine®, Mighty Mouse and
Micro-Crimp® Connectors
Spring-Loaded Microwave Frequency Coaxial Contacts
Size #8 BMA Contacts for DC – 18 GHz
Size 8 5ꢀ ohm microwave BMA coaxial contacts provide mode-free operation from DC to 18
GHz. BMA socket contact features a stainless steel spring mechanism for consistent contact
engagement, and a gold-plated annular interface spring for continuous outer conductor
electrical contact and RFI suppression. Interface conforms to MIL-STD-348 figure 3ꢁ1. Solder
termination. Supplied with cable sealing boot.
