Matched Impedance Coaxial Contacts
for MIL-DTL-38999
Amphenol^® Matched Impedance Size 12 Coaxial Contacts for
RF/Microwave, High Frequency and High Performance Requirements
The matched impedance coax contact is available in size 12. It incorporates a captivated
inner contact which “snaps into” the outer contact preventing displacement or pull back
of the inner contact in situations where the cable may be bent.

Design features and benefits of the Matched Impedance:
• For use in 90 degree angle or bent cable applications
• Provides 50 ohm matched impedance resulting in low VSWR
and low insertion loss
• Frequency range for a mated pair extends to 3 GHz and beyond,
higher than other coaxial contacts previously offered.
• Ideally suited for D38999 high performance and MIL-STD-1760
high band coaxial contact requirements
