Waveguide Couplers

Microwave Techniques manufactures a comprehensive line of waveguide couplers for high-power RF and microwave applications. These devices are available in a diverse range of styles and configurations. We also offer designs with custom specifications, such as heavy wall, reduced height, or custom flange interfaces.

Common waveguide couplers manufactured by Microwave Techniques include: array, monitor, broadwall, directional, cross-guide, branchline, vestigial loop, hybrid couplers, and more.

For standard waveguide directional couplers, these devices are factory set at different coupling values for forward and reverse waves, per application demand. We also have options to optimize space utilization in a feed system layout.

If you do not see the specific waveguide coupler 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.
