 Waveguide Circulators


All catalog part numbers are for devices with clockwise rotation, however, counter-clockwise rotation is available by request.  Pressure sealing and RFI sealing is available for most models.  Flanges are available with any combination of tapped and clear holes.  The part numbers below are for all holes tapped.  CPR grooved flanges are available for some models.  Contact our Customer Service Representatives for special performance and unique mechanical configurations.  We have many other designs not listed here on our website as we develop new designs almost on a daily basis.
