Key Features & Advantages

  • Ultra-Compact Size & Lightweight:Compared to traditional waveguide or stripline circulators, volume and weight are reduced by 50%–80%, with sizes as small as a few millimeters square, making them ideal for highly integrated modules such as T/ R modules and RFIC packages.
  • High Isolation & Low Insertion Loss:High isolation(typically > 20 dB) prevents transmit signal leakage and protects sensitive receivers, while low insertion loss(<0.5 dB) ensures efficient transmission and a low system noise figure.
  • Wide Operating Bandwidth:Supports customizable bandwidths from narrowband(3–5%) to broadband(up to an octave), meeting diverse system requirements.
  • High Power Handling Capacity:Despite compact size, optimized thermal design and materials enable handling several to tens of watts average power, with peak power reaching kilowatt levels.
  • Excellent Temperature Stability & Reliability:Temperature- compensated magnetic circuits or wide - temperature ferrites ensure stable performance from −40 °C to + 85 °C, while a robust structure provides strong resistance to vibration and shock for military and harsh environments.
  • Surface-Mount Technology (SMT) Compatibility:Designed for surface mounting and automated pick- and - place, improving assembly efficiency and consistency while reducing production costs.

Typical Applications

  • Radar Systems: Especially in T/R modules for phased array radars, used to share and isolate transmit and receive channels.
  • 5G/6G Communication Infrastructure: RF units in Massive MIMO base stations for transmit/receive duplexing.
  • Satellite Communication & Navigation: Airborne, shipborne, vehicle-mounted mobile terminals with stringent size and weight requirements.
  • Test & Measurement Instruments: Spectrum analyzers, vector network analyzers, etc., as core switching or isolation components.
  • IoT Devices & Terminals: Drones, wearable devices, and other scenarios requiring compact RF front-ends.
  • Military & Aerospace Electronics: Missile seekers, electronic warfare equipment, etc.
