Dolph Microwave also offer Double Ridged Waveguide Components besides standard waveguide components. The double ridged waveguide components includes coaxial adapter, horn antenna, flexible waveguide, termination, bend, straight&transitions, switch, twist, rotary joint, coupler and Bulkhead Feedthrus etc. The customized requirement can be realized too. For any needs, please contact to sales@dolphmicrowave.com
Dolph Microwave Double Ridged waveguide components, a kind of ridged waveguide components, is to realize wide band requirement that standard waveguide components cannot be offered. It is a rectangular waveguide with a ridge from the top and bottom to offered a lower impedance and wider bandwidth. The types include WRD1800, WRD750-waveguide transfer switch, WRD700, WRD650-e and h plane tee, WRD580, WRD475, WRD200, WRD180 etc. with high performance, high quality, fast delivery but low cost.
Waveguide type: WRD1800, WRD750, WRD700, WRD650-waveguides for dummies, WRD580, WRD475, WRD200, WRD180-waveguide bulkhead etc.
Flange: Flat and groove
Color: White, Black, grey and others.
Dimension: Standard or customized
Treatment: Silver-plated, gold-plated, Chromated
Meterial: Al or Cu
The most obvious features of Double Ridged Waveguide Components is it can be used for impedance matching as they decrease the characteristic impedance of the waveguide. In addition, a wider bandwidth will be offered compared with standard waveguide components. However, the power handling compared with standard waveguide component is lower. Therefore, please based on your actual requirement to select which is suitable. It is mainly used in Radar application, which can be regarded as a rectangular waveguide that bends a wide wall. The electromagnetic field mode is similar to that of the rectangular waveguide, but the field distribution is disturbed due to the edge effect near the ridge.
Double ridged waveguide components is wide bandwidth and low impedance. The dimension is small to offer the precision performance. It can be offered both in Cu and Al.
The main parameters of the ridged waveguide are the cut-off wavelength of the main mode, the single-mode operating bandwidth of the ridged waveguide, the characteristic impedance of the ridged waveguide, the power capacity of the ridge waveguide, and the attenuation of the ridge waveguide.
• Lower cut-off frequency compared to similarly sized non-ridged waveguides.
• Extending higher-order mode frequencies, which may benefit waveguide filter design.
• Replacing planar transmission lines when enhanced power handling is required in tight spaces.
• Wider bandwidth than rectangular waveguides allows the use of a wide range of "transmission lines" like use cases.
