High-Power Differential Phase-Shift Circulator & Isolator
Published circulator and isolator models cover five bands between 2.7 and 36 GHz. Average and peak power, insertion loss, isolation and flange values are model-specific and should be selected from the published table.
Published Performance Range
The differential phase shift configuration is intended for high-power waveguide routing and protection applications. Ratings vary by frequency band and model; use the model matrix below for the published limits.

Engineering Selection for High-Power Waveguide Paths
Match the complete operating band
Select from the published 2.7–3.1, 4.4–5.0, 9.0–11.0, 27.5–31.0 and 30.0–36.0 GHz ranges rather than selecting by waveguide size alone.
Confirm average and peak power separately
Published limits range from 1 to 7 kW average power and 0.1 to 10 MW peak power depending on the selected band.
Verify flange compatibility before release
The published cover-flange designations are UDR32, UDR48, UBR100 and UBR320. Use the flange designation reference at the bottom of this page when checking mating interfaces.

Materials, Finish and Interface Options
Published models use Al/Cu body material options with Chromate/Painted finish. Dolph-MW models include Surtec corrosion-protection treatment and flat-black paint; flanges are unplated, polished and Surtec treated.
Other finishes and paint colors are available upon request. For mating-interface verification, review the Waveguide Flange Standard EIA & IEC reference before finalizing the configuration.
Complete the High-Power Waveguide Path
If the design requires a load at an unused or terminal waveguide port, pair the circulator or isolator with a High Power Termination selected for the same band and interface.
Where the system transitions from rectangular waveguide to a coaxial feed, review the High-Power Waveguide Coaxial Adapter range instead of adding an unverified transition.
If a differential phase shift configuration is not required, review the Waveguide Circulators and Waveguide Isolators product families may provide a more appropriate fit.
