IntelliConnect High Frequency Connectors

Overview
IntelliConnect high‑frequency connectors from Amphenol Military & Aerospace provide reliable interconnect performance from DC through 110 GHz. They combine miniature precision interfaces with controlled‑impedance construction to support microwave and mmWave signal‑paths in aerospace and defense electronic systems.

Interfaces and Configurations
Supported interface series include SMP, SMPM, and SMPS precision push‑on connectors as well as 2.92 mm (K), 2.4 mm, 1.85 mm, and 1.0 mm threaded or slip‑on coaxial types. Each maintains a 50 Ω impedance standard and tight tolerance machining for consistent impedance control and low return loss across the full bandwidth.

Mechanical and Material Characteristics
Connectors feature rugged RF connector construction with high‑precision metal bodies and optimized dielectrics for signal integrity beyond 30 GHz. Mounting styles include board‑mount, cable‑mount, and adapter variants for integration within dense subsystems or test fixtures. Spring‑loaded and blind‑mate designs simplify engagement within tight electronic packages.

Performance and Applications
The connectors are validated through high‑frequency product audits ensuring low‑VSWR performance and stable impedance behavior. Applications span radar modules, electronic warfare transceivers, satellite terminals, and broadband instrumentation links where signal reflection, phase stability, and intermateability are critical.

Integration and Selection Guidance
IntelliConnect high‑frequency connectors integrate seamlessly with Amphenol IntelliConnect adapters and terminations for complete RF paths through mmWave ranges in OpenVPX or SOSA‑aligned systems. When selecting variants, engineers should consider interface type, cable size, and required frequency bandwidth to ensure the best electrical match and mechanical layout for the intended architecture.
