Y-Junction Waveguide Circulators

Mi-Wave’s 179 is an H-plane, three-port Y-junction ferrite device. All external mating surfaces are machined to extreme flatness to provide connection to standard waveguide flanges for minimum discontinuity. The 179 Series circulators are available in standard waveguide sizes from 18.0 to 110 GHz, in round-style flanges only.


  • Low Loss
  • Low VSWR
  • High Isolation
  • Broad Bandwidth
  • Compact & Rugged
  • Optimal Temperature Response
