Amphenol CDI High Frequency Connectors

Amphenol CDI high‑frequency connectors provide rugged, precision‑machined coaxial interfaces engineered to maintain broadband signal integrity across the microwave and mmWave spectrum. Built under Amphenol Military & Aerospace’s stringent manufacturing standards, these connectors serve mission‑critical systems demanding consistent 50 Ω impedance control and repeatable low‑VSWR engagement.

Interface Families

• SMP / SMPM / SMPS precision push‑on connectors — for blind‑mate, high‑density packaging of radar and EW modules.
• 2.92 mm, 2.4 mm, 1.85 mm and 1.0 mm coaxial series — supporting DC to 110 GHz operation for instrumentation and test applications.

Design and Performance

• 50 Ω system impedance with tight tolerance impedance control.
• Low‑VSWR interfaces for accurate phase and amplitude stability at multi‑GHz frequencies.
• High‑precision mating surfaces and floating‑mount contact design to reduce mechanical stress.
• Plating and materials suited for Amphenol’s aerospace‑grade corrosion and environmental requirements.

Integration Options

• Available as board‑mount receptacles, bulkhead feed‑through connectors, and cable‑mount plugs.
• Compatible with Amphenol CDI adapters and terminations for test, load, and between‑series transition needs.
• Intermates with standard 2.92 mm, 2.4 mm, and 1.85 mm coax series for broadband test and metrology chains.

Applications

• Radar and electronic warfare modules requiring compact mmWave interconnects.
• SATCOM and telemetry links with continuous DC‑to‑110 GHz bandwidth.
• Broadband instrumentation and precision test environments where phase stability and mechanical repeatability are critical.

Together with Amphenol CDI Adapters & Terminations and other AMAO subsidiaries, these connectors form a complete high‑frequency portfolio supporting metrology‑grade connectivity for defense and aerospace systems.
