90° Waveguide Power Divider & Combiner
Built for waveguide systems that need controlled power splitting or combining with phase requirements. The product family is available in H-plane and E-plane layouts, with standard and custom flange, material and way-count options.
Dolph Microwave waveguide power divider / combiner. Open the official PDF for published model data and ordering information.
Start with the parts that affect fit and RF performance
For a useful quotation, frequency alone is not enough. The waveguide size, number of ways, H-plane or E-plane layout, flange face and power level all matter. If you already have a mating drawing, send it with the inquiry.
Product family stated as WR2300 to WR10. Current webpage model rows run from WR430 to WR28.
2, 4, 6, 12 and other configurations are stated at family level. Current webpage rows list 1-2, -4 and -8 ways.
H-plane and E-plane options are listed. Isolation data differs by type in the webpage table.
Aluminum (Al) and Copper (Cu) are stated on the webpage. The older brochure also shows Al/Brass in its summary table.
Cover, grooved and choke options are stated at family level. Exact cover/grooved designations are model-specific.
The webpage describes high-power handling without a single universal rating. Confirm CW/peak power for the exact build.
Match one complete configuration, not isolated “best” numbers
Use one model row as the starting point, then confirm any custom electrical or mechanical requirements against the quotation and drawing. Do not combine the lowest VSWR, widest frequency range or different flange codes from separate references and treat them as one part.
- Frequency: send the required operating band, not only the waveguide size.
- Power: include CW and peak power when applicable.
- Ports: state the required way count and H-plane or E-plane layout.
- Mechanical: provide flange standard, envelope, orientation and any mating drawing.
- Documentation: state whether you need PDF data, STEP, test data or drawing approval.

The webpage source lists WR75 flange designations as UDR100/UBR100 and PDR100/PBR100, and WR187 grooved flanges as PDR348. These values are reproduced as published; confirm the applicable flange on the quotation or drawing before order release.

Brochure reference data
The product brochure currently linked from the page contains additional published data that is not the same as the newer webpage table. It is useful as a reference, but the selected model should be confirmed before purchase.
Webpage ordering code example
Finish and corrosion protection
All Dolph-MW models include a 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.
The downloadable brochure separately lists “Iridite per MIL-C-5541” for inside finish and “Anticorrosion Black Painted” for body finish. Confirm which finish note applies to the exact quoted part.
Where this product family is used
Telecommunications
Waveguide signal distribution or combining where the system design includes controlled phase relationships.
Radar systems
Distribution paths feeding antenna or RF subsystems that require repeatable waveguide interfaces.
Satellite communications
Waveguide networks used in uplink, downlink or antenna-feed assemblies.
Electronic warfare
RF systems in which phase-controlled signal routing is part of the defined equipment architecture.
Research & development
Lab and prototype setups that need waveguide signal division, combination and phase-control experiments.
Custom RF assemblies
Projects where flange choice, way count, mechanical envelope or electrical targets require a configuration review.
Send the information an engineer can actually quote from
You do not need to know the final model number. Send the operating conditions and mating interface; the configuration can then be checked against the published range.
Continue the technical check
Have a frequency band, flange and power level already?
Send those details with the required number of ways and any mechanical drawing. Ask for the complete part number, applicable test data, rated power and matching PDF/STEP documentation before order release.
