Waveguide Twists



Microwave Techniques manufactures waveguide twists for high-power RF and microwave applications, available in several configurations and design types.

We recommend the use of twists when mechanical system packaging requires a change in the plane of polarization. Our compact three-step twist exhibits a VSWR less than 1.05:1 over a 10% bandwidth. Lower VSWR’s or increased bandwidth can be realized by utilizing a five-step twist.

Twist angles of 30°, 45°, 60° are also available. Continuous or smooth twists are available in the smaller waveguide sizes. All units come in right-hand (RH) or left-hand (LH) twist versions.

If you do not see the specific waveguide twist 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.

  • 1:00:1 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.
