Part Number Guide
Finish and Surface Treatment
All Dolph-MW models include Surtec/corrosion-protection treatment and are painted flat black. Flanges are unplated, polished and Surtec treated. Other finishes and paint colors are available upon request.
Use the Drawing to Lock the Build
Send the mating flange, available envelope and mounting constraints with the RF requirement. For a larger routed assembly, Dolph can review the divider/combiner together with double-ridged straight sections or a custom waveguide assembly.
Published Application Areas
Send the Data That Controls Fit and Performance
For a WCDW/WCDWI catalog match or custom mechanical configuration, send the operating band, WRD size, required 2-, 4- or 8-way configuration, isolation option, flange type, average and peak power information, quantity and drawing or sketch.
Manufacturing and Verification
Dolph publishes in-house CNC machining, turning, waveguide forming and bending, brazing, assembly, anodising/passivation, plating and electroforming. Dimensional inspection includes coordinate measurement, and published RF vector/scalar measurement capability reaches 100 GHz.
Quality References
Request current quality records.
Request applicable process-compliance records.
Defective material and workmanship are covered for one year from delivery, subject to the published warranty terms.
Dolph states that it has made and tested microwave parts in its Xi’an factory since 2001.
Related Components for the Same RF Path
If the divider/combiner is only one part of the assembly, select the adjoining interface at the same time so the WRD size, flange and mechanical envelope remain consistent.
Waveguide Tees
Use E-plane, H-plane or Magic Tee functions when the junction requirement is different from this divider/combiner family.
Waveguide to Coaxial Adapter
Use when one side of the system must transition from a WRD interface to coaxial N, SMA or 2.92 mm connector configurations in the published adapter range.
WG Power Divider / Combiner In Phase 90°
Use the separate standard-waveguide family when the design specifically calls for a 90° phase relationship rather than this double-ridged configuration.
