Our 75kw microwave circulator operates at 915MHz, and is fully compatible with WR975 waveguide. Our circulator solutions place emphasis on the selection and bias point of ferrite material. This will minimize insertion loss and maximize isolation at the desired frequency, bandwidth and power level of interest. Our robust designs emphasize high peak and average power levels. We offer convection cooled, as well as liquid cooled units.

We specialize in circulators for precise and exacting applications. We place the same level of intricate detail into our circulators specific for industrial microwave systems. When failure isn’t an option, our high power 75kW circulators provide you with unique capabilities in protection and detection.
