Rectangular Waveguide Transitions

​Product Overview​​

Dolph Microwave’s precision-engineered Double-Ridge to Rectangular Waveguide Transitions enable seamless integration between double-ridge and standard rectangular waveguide systems, optimized for frequencies from 2.6 GHz to 40 GHz. These transitions achieve exceptional performance with a maximum VSWR of ​​1.06:1​​ in shared frequency bands and typical VSWR of ​​1.15:1​​ across models, ensuring minimal insertion loss and impedance matching. Constructed from lightweight aluminum with chromate conversion and gray epoxy enamel finishes, they comply with RoHS and REACH standards, offering durability in demanding environments.

​​Key Features​​

• ​​Low VSWR​​: Engineered for ultra-low reflection (1.06:1 to 1.15:1) to maintain signal integrity.
• ​​Broad Compatibility​​: Supports transitions between WRD, UDR, and UBR waveguide series, including over-moded designs for harmonic absorption testing.
• ​​Customizable Configurations​​: Tailored narrowband solutions and length options (e.g., 50 mm to 180 mm) for specialized applications.
• ​​Robust Construction​​: Aluminum material with corrosion-resistant Surtec® treatment and optional custom finishes.

​​Applications​

​Ideal for radar systems, 5G infrastructure, millimeter-wave communications, and satellite networks, these transitions bridge test equipment compatibility gaps. They are critical for evaluating double-ridge components using rectangular waveguide setups or validating harmonic filters in industrial heating and microwave chemistry systems.

​​Compliance & Customization​

​All transitions include Surtec® anti-corrosion treatment and default flat-black epoxy paint. Optional finishes, materials (e.g., copper), and flange types are available for specialized requirements. Detailed datasheets (DWG/STEP) and part number guides (e.g., DH-350DRT70WA80PPA) provide clarity on waveguide size, length, and flange compatibility.

Designed for laboratories and industrial settings, Dolph Microwave’s transitions ensure accurate, repeatable measurements while suppressing higher-order modes for reliable wideband testing. Contact the team for tailored solutions or specific frequency band adaptations.
