Double Ridged Waveguide Twists

Flexible twistable waveguide is divided into left-handed and right-handed according to the twisting direction. The standard twisting angle is 90 ®. Other twisting angles can be customized. Dolph Microwave provide a wide variety of double ridged waveguide assemblies specially designed for every customers unique requirements.

FAQs of Double Ridged Waveguide Twists
Advantage of Double Ridged Waveguide Twists
Double-ridged microwave waveguide twists provide accurate electrical and mechanical interface. It can realise the different angle rotation of the rectangular waveguide.

Different to conventional waveguide twist, the outstanding advantages of this structure are the ease for manufacture, compact size, and low return loss.

Application of Double Ridged Waveguide Twists
The double ridge twist waveguide is extensively applied in engineering application, especially for satellite communication.
