Characteristics and Common Issues of Double Ridged Waveguides
Dolph Microwave double ridged waveguide components are a type of waveguide component designed to meet broadband requirements that standard waveguide components cannot provide. It is a rectangular waveguide with a ridge on the top and bottom to provide lower impedance and wider bandwidth. Models include WRD1800, WRD750, WRD700, WRD650, WRD580, WRD475, WRD200, WRD180, etc. It has high performance, high quality, fast delivery, and low cost.

Ⅰ. Characteristics of double ridged waveguide components

The most obvious feature of the ridged waveguide is that they can be used for impedance matching because they reduce the characteristic impedance of the waveguide. In addition, relative to standard waveguide components, they will provide wider bandwidth. However, compared to standard waveguide components, they have lower power handling.

Therefore, choose according to your actual needs. It is mainly used in radar applications and can be regarded as a rectangular waveguide with a bent wide wall. The electromagnetic field mode is similar to a rectangular waveguide, but the field distribution is disturbed due to edge effects near the ridges.
