Application of Rectangular Waveguide and Applications of Circular Waveguide

Dolph Microwave Double-ridge waveguide tubing are rectangular waveguide design tube with two ridges protruding parallel to the short wall. Double-ridge waveguide tube are widely used in antenna and microwave systems since they exhibit low cut-off frequency, broad frequency band, low characteristic impedance, and capability of matching to coaxial cable.

Feature of Double Ridged Waveguide Tube

Double ridged rectangular waveguide and circular waveguide tube is an electromagnetic feed line that is used for high frequency signal, and it conducts microwave energy at lower loss than coaxial cables.

Application of Double Ridged Waveguide Tube

The double ridge waveguide tube is used in microwave communications, radars, aerospace, radars, aerospace, telecommunications, and other high frequency applications.

It could be simply used as a transmission line, besides, to be used to make various passive components like a filter, coupler, magic T, etc.

Procurement suggestions

A specialized rectangular waveguide with dual internal ridges to lower cutoff frequency and enhance bandwidth for microwave/RF applications (e.g., radar, satellite comms). Typically made of oxygen-free copper or aluminum with precise dimensional tolerances (<±0.05 mm) to minimize insertion loss and mode distortion. (for reference only)
