70-86 GHz Bandwidth

  • Wideband (24% fractional bandwidth)
  • Internal waveguide screw access
  • Anti-cocking waveguide flanges
  • Resists stray magnetic fields
  • Comprehensive test data
  • Low insertion loss

Asymmetry
Unlike the Y junction circulator, the hybrid circulator is asymmetric. The path from port 3 to port 1 is internally terminated as shown in the schematic to the right and verified by the S13 trace in the measured data below. On request, the hybrid circulator can be assembled in a way that restores symmetry if needed.
