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, with options also available for MIL-DTL-5015, MIL-DTL-22992, and various rectangular rack and panel connectors. Amphenol also provides transition adapters for seamless integration with printed circuit boards and offers cable assembly and testing services to ensure complete interconnect solutions.
