Waveguide High-Power Loads



Microwave Techniques manufactures waveguide high-power loads for microwave and RF applications. High-power loads are offered in several configurations. Air cooled loads are available to handle most medium power applications, while numerous styles of water cooled loads are available for high power applications.

Our comprehensive line entails several design types and configurations for low, medium, and high-power settings. Whether your project requires air cooled, liquid cooled, super high power, or minimum cost and weight objectives, Microwave Techniques has a wide ranging portfolio of loads for customers to select from.

Microwave Techniques sales engineers are readily available to discuss custom load requirements.

If you do not see the specific waveguide high-power load you require, contact sales@microwavetech.com to discuss your exact product requirements with a technical sales engineer.

  • Unpressurized Waveguide
  • 1:00:1 VSWR
  • Average power is based upon unpressurized painted aluminum waveguide, internal surface finish of 63µm, under free convective cooling with an operating temperature that is 25oC above ambient temperature. Cooling options should be considered if the waveguide will be operating at higher average power levels - please consult factory.
