• Application

  1. Aerospace & Radar Systems

  • Radar Systems: waveguide to coaxial adapter are used to connect the waveguide feed network at the antenna end with the coaxial Transmit/Receive (T/R) modules at the backend. They must guarantee signal phase consistency, especially in high-frequency bands (such as X-band and Ku-band);
  • Electronic Jamming Systems: Used in signal transmit and receive chains, requiring extremely low Voltage Standing Wave Ratio (VSWR) to ensure signal purity;
  • Telemetry Systems: In high-vibration and high-impact flight environments, right-angle or ruggedized transitions provide reliable electrical connections.

  2. Satellite Communications (Satcom)

  • Ground Station Tx/Rx: Waveguide to coaxial adapter connects the waveguide output of parabolic antennas with the coaxial inputs of Low Noise Amplifiers (LNA) or Power Amplifiers (PA).
  • Satellite Payload Testing: During ground verification of satellite payloads, high-performance transitions are used to simulate signal transmission in a space environment, ensuring test accuracy. Inter-Satellite Links: Within satellites, compact waveguide-to-coaxial structures are often used to save space and reduce weight.

  3. Test & Measurement

  • Antenna Testing: Connects waveguide antennas to Vector Network Analyzers (VNA). Especially in the millimeter-wave band (26.5GHz–110GHz), high-precision transitions (such as 2.4mm or 2.92mm connectors) are required. Anechoic Chamber Testing: Transitions are used to route signals from waveguide transmission lines into coaxial test equipment within EMC chambers. Automated Test Equipment (ATE): Right-angle adapters are often used in space-constrained test fixtures to optimize layout.

  4. Wireless Communications (5G/6G & Microwave Relay)

  • 5G/6G Millimeter-Wave R&D: Used in base station prototyping and testing to connect millimeter-wave chips/modules with test equipment. Point-to-Point Microwave Communication: Used for signal coupling and monitoring in long-haul microwave transmission links.

  5. Industrial, Medical & Scientific Research

  • Industrial Microwave: Power monitoring in microwave heating and drying equipment. 
  • Medical Microwave: Signal transmission in microwave physiotherapy and tumor hyperthermia equipment. 
  • Large-Scale Scientific Facilities: Used in particle accelerators and radio telescopes (e.g., FAST) for high-power, low-noise signal transmission.

• Packing and Shipping

Our Waveguide to coaxial adapters are carefully packaged to ensure maximum protection during transit. Each connector is individually wrapped in anti-static material and placed in a sturdy, cushioned box to prevent any damage from shocks or vibrations.

The packaging is clearly labeled with product information, including part numbers and specifications, to facilitate easy identification and inventory management.
