Waveguide Windows

Microwave Techniques manufactures waveguide windows for high-power RF and microwave applications. Our windows, gas barriers, and pressure windows are available with standard or custom options. We offer compact designs for minimum transmission loss and maximum power handling.

For the best possible performance, we recommend that your microwave feed system be maintained under a slight positive pressure. This helps to prevent the entrance of moisture or other contaminants. In our design of waveguide windows, we utilize the newest dielectric materials to ensure high power handling capabilities and optimum functionality.

If you do not see the specific waveguide window 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.
