Key Engineering Advantages

Multi-Technology Integration

Combines RF, FORJ, contactless, wave guides, and fluidic channels.

Special Materials

Manufactured from aerospace-grade materials for extreme reliability.

Testing & Traceability

Complete documentation and rigorous testing protocols.

Radar antenna systems—deployed in air traffic control, maritime navigation, meteorological stations, and military targeting systems—rotate continuously to sweep the surrounding environment. To link the rotating antenna assembly to the stationary base receiver, a hybrid rotary joint must transfer electrical power, auxiliary control signals, high-frequency radio waves (RF), and fiber optic data.

High-Performance Radar Challenges

  • Radio Frequency (RF) Signal Integrity
    High-frequency coaxial lines must support frequencies up to 18 GHz and beyond with minimal signal loss or VSWR fluctuations.
  • Waveguide Integration
    The need to route high-power microwave signals via specialized waveguides.
  • Fiber Optic Rotary Joints (FORJ)
    Utilizing contactless optical channels for ultra-high-speed data, ensuring electromagnetic immunity.
  • All-Weather Reliability
    Operation in sub-zero alpine conditions or corrosive marine salt air.

Custom Hybrid Through-Bore & Ruggedized Solutions

  • RF & Waveguide Customization
    Combined electrical lines with single-channel or multi-passage RF joints (up to 18 GHz, using SMA connectors) and waveguide interfaces.
  • Fiber Optic Integration
    Contactless single-mode or multi-mode FORJs that guarantee unlimited rotational life.
  • Environmental Resistance
    Stainless steel or ruggedized housings rated to IP65/IP67, with options for integrated heaters to prevent freezing.
