Broadband Coaxial Circulator

Key Features & Advantages

  • Ultra-wideband coverage across multiple models with broad frequency ranges (e.g. 0.5–2GHz 1–4GHz 2–8GHz 6–18GHz), meeting diverse applications while reducing component variety and simplifying system design.
  • Very low insertion loss (typ. < 0.4 dB), maximizing signal transmission efficiency while enhancing system signal-to-noise ratio (SNR) and dynamic range.
  • Excellent isolation (typ. > 20 dB), effectively preventing transmit signal leakage into the receiver to protect sensitive components and significantly improve overall system performance.
  • High power handling capacity with options for high average power (hundreds of watts) and peak power (kilowatts), ensuring stable and reliable operation in harsh high-power environments.
  • Superior VSWR (typ. < 1.25), ensuring good impedance matching, reduced signal reflection, and reliable signal integrity.
  • Robust coaxial structure with standard interfaces (e.g., SMA, N-type, TNC) and a hermetically sealed housing, providing strong shielding and mechanical strength for harsh environments.
  • Outstanding temperature stability across a wide range (e.g., -55°C to +85°C), ensuring reliable performance under diverse climatic conditions.

Typical Applications

  • Radar Systems: Used as Transmit/Receive (T/R) switches, protecting the receiver from high-power transmit pulses.
  • Wireless Communication Systems: Separates transmit and receive signals between the Power Amplifier (PA) and antenna, improving system capacity and sensitivity.
  • Test & Measurement Equipment: Used with signal sources, spectrum analyzers, and network analyzers to protect expensive instruments from reflected signals.
  • Electronic Countermeasures (ECM) Systems: Enables signal routing and isolation in jamming and surveillance systems.
  • Satellite Communications: Used for signal combining and splitting, ensuring isolation between uplink and downlink paths.
