Waveguide Test Termination Loads

Microwave Techniques manufactures waveguide test termination loads for high-power microwave and RF applications. We offer a wide range of waveguide terminations ranging from instrument level, low power test terminations, to very high-power system loads.

The low power waveguide test terminations may be supplied in either a fixed or sliding configuration to best meet the needs of each requirement.

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

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

Please note all product data, specifications, and descriptions are subject to change at the sole discretion of Microwave Techniques and must be confirmed at the time of order.

¹ 30,000 V/cm Breakdown Voltage 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.
