Product Categories and Features:
Quadrax Contacts
Designed for high data transfer rates, low power consumption, and excellent EMI compatibility. They feature four strategically spaced inner contacts forming two 100 or 150 Ohm matched impedance differential pairs. Available in size 8, with crimp termination and PC tails. Requires modified MIL-DTL-38999 connectors for keyed contacts.
Split-Pair Quadrax Contacts
An advancement offering higher bandwidth (up to 6.5 Gbps per pair) and enhanced crosstalk performance compared to standard quadrax. Compatible with shielded twisted pair cables and suitable for applications like 10/100/1000/10GBASE-T Ethernet, DVI, USB 2.0/3.0, Serial Rapid IO, PCI-Express 2.0, HDMI 1.3a, and SATA 2.0.
Differential Twinax Contacts
Provide high data transfer rates, low power consumption, and excellent EMI compatibility. Feature two strategically spaced inner contacts forming one 100 or 150 Ohm matched impedance differential pair. Available in size 8, with crimp termination and PC tails. Requires modified MIL-DTL-38999 connectors for keyed contacts.
Coaxial Contacts
Designed for RF/microwave and shielded wire applications, offering shielding protection and RF/microwave performance. Available in sizes 4, 8, 12, and 16. Can be mixed with standard contacts in MIL-DTL-38999 connectors. High-frequency variants (DC to 40 GHz) with Float Mount technology are available for consistent microwave performance.
Matched Impedance Coaxial Contacts
Available in size 12, these contacts offer 50 Ohm matched impedance with low VSWR and insertion loss, suitable for 90-degree angle or bent cable applications. Frequency range extends to 3 GHz and beyond.
Concentric Twinax Contacts
Designed for protection from magnetic and electrostatic interference, including nuclear electromagnetic pulse. Available in sizes 8 and 12, suitable for MIL-STD-1553B data bus applications. Maintain shield integrity and do not require contact polarization.
Triax Contacts
Provide additional shielding when terminated to triax cable. Available in sizes 8, 10, and 12, with three conductors separated by dielectric insulation for isolated ground planes and improved shielding. Can be specified for direct connection to printed circuit boards.
Transition Adapters
Quadrax and Differential Twinax transition adapters facilitate launching controlled impedance signals to printed circuit boards. Available in 90 or straight receptacles, threaded or cable-to-board styles. Micro D-Twinax transition adapters offer push-pull quick disconnect coupling in miniature sizes.
Cable Systems and Testing
Amphenol provides a wide array of cable assemblies with high-speed contacts and performs rigid 100% testing on all cable assemblies, including DWV, resistance, and continuity tests.
Connector Compatibility
These high-frequency contacts are primarily designed for MIL-DTL-38999 Series I, II, and III connectors. They can also be incorporated into other Amphenol connector series, including Heavy Duty Circular Connectors (MIL-DTL-22992), Printed Circuit Board Connectors, LRM Interconnects, and ARINC 600 and R27 Rack & Panel Connectors.
