Amphenol Aerospace offers a comprehensive range of high-frequency contacts designed for demanding applications in military and commercial aviation, military vehicles, missiles, and C4ISR systems. These contacts, including coaxial, twinax, triax, quadrax, and differential twinax types, are engineered for superior electrical performance, high data transfer rates, and excellent EMI compatibility. They are primarily designed for integration into MIL-DTL-38999 series circular connectors, providing reliable interconnection solutions for high-speed and high-frequency signal transmission up to 40 GHz. Amphenol also provides complementary transition adapters and cable assembly services to support complete system integration.
