Double-Ridged Waveguide Straights
Double-ridged waveguide straight sections connect compatible WRD interfaces over the operating band of the selected model. Specify WRD size, flange pair, finished length, material and finish. The loss and VSWR values must correspond to that length and configuration, not to a different row in the catalog.
Define the WRD size, finished length and flange pair.
Double-ridged waveguide straight sections provide a fixed RF path between compatible WRD interfaces. Select the operating band, ridge geometry and flange pair together; an ordinary rectangular guide with a similar outer envelope is not an interchangeable interface. Dolph lists model-specific frequency, VSWR, insertion loss and length data in its double-ridged catalog.
Send the Waveguide RequirementSend the details that control the final configuration
WRD size
Identify the double-ridged waveguide size at each end.
Operating band
Send the actual minimum and maximum frequency.
Finished length
State the required length and any envelope limit.
Flange pair
Cover/grooved flange designation and mating standard.
Length and RF performance must remain tied to the selected catalog row.
Confirm the finished flange-to-flange length and its dimensional reference on the approved drawing. The catalog length field alone does not establish which lengths share the stated insertion loss or whether end flanges are included.

Confirm the final length, flange pair and finish on the current drawing. Do not combine the lowest loss, widest band and longest length into one family-wide guarantee.
Match RF and mechanical limits in one review.
Provide both mating interfaces, the operating band and the installation envelope. The returned configuration should reference the exact model row or a drawing-controlled custom build.
RFQ checklist
- WRD size at both interfaces
- Operating band
- Finished length and routing constraints
- Flange designation, material and finish
Continue with the matching component family
Use when the two waveguide interfaces or sizes differ.
Use where repeated connection or service access is required.
Use when one side of the RF path is coaxial.
Ready for a model check?
Send the WRD designation at both ends, operating band, flange drawings, finished length and available envelope. Add insertion-loss and return-loss limits when the section is part of a measured RF path.
