Amphenol Military & Aerospace’s Amphenol CDI division manufactures Standard RF Connectors serving as the foundation for many microwave and communication architectures across defense and aerospace platforms. Each connector maintains a 50 Ω impedance and is constructed for mechanical reliability and stable electrical performance under vibration, temperature, and repeated mating conditions.
Interface Options
- SMA Connectors: Threaded subminiature interface suited for general microwave and avionics use.
- SMP / SMPM Series: Precision push‑on interfaces enabling blind‑mate, high‑density packaging in compact modules.
- BNC and TNC Types: Bayonet and threaded coupling styles used in instrumentation and field‑replaceable RF assemblies.
- N‑Type and SMB Series: Larger and quick‑connect options for low‑frequency or higher‑power signal lines.
Construction and Performance
CDI connectors employ rugged RF connector construction techniques including corrosion‑resistant alloys, precision CNC machining, and controlled plating systems to maintain low VSWR across broad operating bands. Mating interfaces are designed for repeatable impedance control, ensuring minimal reflection and insertion loss through DC‑to‑microwave frequencies.
Integration Characteristics
- 50 Ω system impedance compatible with standard coaxial line architectures.
- Multiple mount options including panel, cable, and board‑mount styles for flexible system integration.
- Available terminations support solder, crimp, and PCB tail variants.
Applications
These Standard RF Connectors are widely used in radar system interconnects, SATCOM ground stations, electronic warfare feedlines, and airborne avionics modules. Their mechanical durability and broad bandwidth support make them equally suitable for laboratory test equipment and legacy platform support programs.
Selection Guidance
Engineers should choose Amphenol CDI Standard RF Connectors when platform design calls for proven connector families compliant with MIL‑PRF‑39012 and similar MIL‑SPEC references. For higher‑frequency or metrology‑grade applications above conventional microwave range, refer to Amphenol CDI High Frequency Connectors. Where precision transitions or RF loads are required, Amphenol CDI Adapters & Terminations complement these standard series.
