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.
