Faraday Isolators


RPG offers a series of fullband Faraday isolators. They cover the frequency range of 50 to 220 GHz. These isolators are Faraday rotation type ferrite devices with bandwidths covering a full waveguide band. They are compact and lightweight and provide much greater isolation than waveguide junction isolators. Our Waveguide Faraday Isolators (WFI) are available for various waveguide bands.

Features:

  • Low insertion loss
  • Coverage of Full Waveguide Band
  • 33 to 220 GHz
  • Compact size
 

Applications:

  • Measurement and instrumentation
  • Millimeter wave receiver
  • Broadband or swept frequency applications
  • Wideband measurement systems
