Double Ridge Waveguide-Transition

Product Overview​​

Dolph Microwave’s Double-Ridge Waveguide Transitions provide high-performance interconnects for seamless signal transmission between double-ridge waveguide systems operating across 3.5 GHz to 18 GHz. Engineered for precision, these adapters minimize insertion loss (typical VSWR ≤1.15:1) while ensuring optimal impedance matching across overlapping and multi-band frequency ranges. Constructed from robust gold-plated or corrosion-resistant painted brass, they are ideal for high-power applications requiring reliability in harsh environments, such as radar, SATCOM, and MILCOM systems. With waveguide sizes spanning WRD-350 to WRD750, these transitions support flexible system integration while maintaining signal integrity up to 18 GHz.

​​Key Features​​

The waveguide transitions feature a tapered design for smooth modal conversion, reducing reflections and achieving a voltage standing wave ratio (VSWR) as low as 1.08:1 across specified bands. Rugged aluminum or brass construction, combined with Surtec corrosion-resistant treatment and flat-black paint, ensures durability in outdoor or high-humidity deployments. Flange configurations include flat (FPWRD) and grooved types, compliant with MIL-STD standards for secure mating. Customizable finishes and materials are available to meet specific environmental or electrical requirements.

​​Applications​​

These adapters are critical in aerospace telemetry, scientific research instrumentation, and telecom infrastructure where multi-band waveguide systems demand low-loss transitions. Their ability to handle high power densities (up to 1 kW average) makes them suitable for radar pulse transmission, satellite ground stations, and RF testing environments requiring repeatable performance.

​​Compliance & Customization​​

All transitions comply with RoHS and REACH regulations. Optional finishes, including MIL-SPEC gold plating or custom paint colors, are available upon request.
