RF Cable, Connectors & Cable Assemblies

Baseline 50 Ω RF and microwave cable assembly family integrating standard SMA, SMP, TNC, BNC, N‑Type, and SMB connectors with Amphenol Military & Aerospace cable technologies. Provides low‑VSWR performance and durable construction across flexible, semi‑rigid, and specialty variants for radar, SATCOM, EW, and test applications.

Available From: Amphenol CDI, Amphenol CIT, EZ Form Cable, IntelliConnect, Micro-Coax, SV Microwave, Times Microwave

Amphenol Military & Aerospace Standard Interface Cable Assemblies form the foundation of the organization’s 50 Ω coaxial interconnect portfolio. They combine proven connector standards such as SMA, SMP, SMPM, TNC, BNC, N‑Type, and SMB with a range of cable constructions engineered for signal integrity and durability in demanding defense and aerospace environments.

Comprehensive RF Assembly Portfolio

This grouped family brings together multiple sub‑series designed to meet different mechanical and electrical requirements:

  • Semi‑Rigid RF Cable Assemblies – Metal‑sheathed designs offering stable impedance and shielding for fixed routing.
  • Flexible and Low Loss RF Cable Assemblies – Phase‑stable, low‑attenuation lines suited to dynamic or vibration‑exposed installations.
  • High Performance RF Cable Assemblies – Precision broadband assemblies supporting operation across microwave and mmWave frequencies.
  • Harsh Environment RF Cable Assemblies – Hermetically sealed and vapor‑protected configurations qualified for extreme conditions.
  • Small Form Factor and Cryogenic Variants – Miniature or specialty configurations for compact and temperature‑critical systems.

Design and Engineering Considerations

Each assembly maintains broadband 50 Ω impedance control with low VSWR termination to minimize reflection. Options include semi‑rigid copper‑tin composite, formable, and low‑loss PTFE‑ or SiO₂‑based dielectric structures to balance mechanical flexibility, attenuation, and environmental protection. Assemblies can integrate standard interface connectors directly or via hybrid transitions such as ConvergeRF for mixed‑diameter cable routing.

Applications and System Integration

Standard Interface Cable Assemblies are used throughout radar, electronic warfare, satellite communications, avionics, and laboratory test infrastructures. Their consistent impedance and mechanical precision allow interchangeability across Amphenol divisions—including SV Microwave, Times Microwave Systems, EZ Form, CDI, and IntelliConnect—ensuring backward compatibility and broad integration with existing 50 Ω system architectures.

Selection Guidance

Engineers can select assemblies by balancing frequency range, flexure requirement, and environmental exposure:

  • Use semi‑rigid or formable styles for high‑frequency, fixed installations requiring precision phase match.
  • Choose low‑loss or high‑performance lines for extended microwave or mmWave bandwidth.
  • Specify harsh‑environment assemblies for sealed or high‑vibration missions.
  • Apply small‑form factor assemblies where space and weight constraints dominate.

All variants adhere to Amphenol’s rigorous RF performance audit and dimensional verification process ensuring mechanical repeatability and broadband 50 Ω conformance across the product family.
