Microwave Terminations
Resin Systems provides a complete line of microwave terminations in waveguide sizes from WR650 through WR28 in rectangular, and WRD350 through WRD750 in double ridge. All Resin Systems standard microwave terminations are manufactured from 6061 aluminum with cover flanges. Other materials, flange configurations, and pressurized units are available in custom designs. Using our RS-4200CHP ceramic load material, which is fired at 1300°C, the loads can withstand temperatures up to 500°C when properly finned.
