Product Overview​

​Dolph Microwave’s Double-Ridge Waveguide Pressure Windows are precision-engineered solutions designed to environmentally isolate waveguide systems while maintaining optimal RF performance. These windows support frequencies from 0.84 GHz to 40 GHz (model-dependent), handle pressures up to 45 PSIG, and sustain average power levels up to 1,000 W (800 W for high-frequency models). Constructed with low-loss materials such as Teflon, fiberglass, or ceramics, they ensure minimal insertion loss (VSWR ≤1.15:1) and robust protection against moisture, dust, and corrosive environments. Ideal for high-power and mission-critical applications, they are available in waveguide sizes from WRD840 to WRD180.

​​Key Features​

  • ​​Broad Compatibility​​: Compatible with waveguide sizes WRD840 to WRD180, covering frequency ranges up to 40 GHz.
  • ​​High-Pressure Resilience​​: Rated for pressures up to 45 PSIG, ensuring reliability in harsh environments.
  • ​​Material Versatility​​: Choose from Teflon, fiberglass, or ceramic windows; aluminum or copper alloy flanges with iridite, chromate, or silver-plated finishes.
  • ​​Low-Loss Design​​: Optimized for VSWR below 1.15:1 to minimize signal reflection and maximize power transfer.
  • ​​Custom Configurations​​: Optional flange types (flat or grooved), pressure gauges, and specialized finishes (e.g., Surtec corrosion protection).

​​Applications​​

These pressure windows are integral to systems requiring environmental sealing and high-power RF integrity, including radar systems for military/aviation, satellite communications (SATCOM) ground stations, aerospace telemetry, and scientific research setups involving vacuum or pressurized chambers. Their corrosion-resistant construction also makes them suitable for marine and industrial environments.

​​Additional Notes​​

All Dolph Microwave waveguide windows undergo rigorous polishing and Surtec anti-corrosion treatment. Standard units are unpainted but can be customized with colors or specialized coatings. For vacuum-sealed applications, ceramic or quartz materials are recommended. Consult our RF engineering team for tailored solutions, including non-standard waveguide sizes or extreme environmental compliance.

Product Overview​​

Dolph Microwave’s Double-Ridge Waveguide Standoffs and Hangers are precision-engineered aluminum clamps designed to secure waveguides in E-plane or H-plane configurations across critical RF and microwave systems. Compatible with standard WRD waveguide sizes (e.g., WRD840 to WRD180), these components operate across broad frequency ranges from 0.84 GHz to 40 GHz, ensuring low-loss signal transmission. Each unit includes corrosion-resistant stainless steel hardware and undergoes Surtec chromate treatment with flat-black paint for durability in harsh environments. Ideal for radar, telecom, and aerospace applications, they comply with RoHS/REACH standards and support custom configurations upon request.

​​Key Features​​

Engineered for versatility, these standoffs and hangers integrate seamlessly with rectangular and double-ridge waveguides, offering robust mechanical stability in both indoor and outdoor installations. The aluminum construction reduces weight without compromising strength, while stainless steel mounting kits ensure long-term reliability. Pre-assembled hardware enables quick deployment, and optional customizations—such as alternative finishes or non-standard waveguide sizes—address specialized project requirements.

​​Applications​​

Deployed in high-performance systems, these components are critical for maintaining waveguide alignment in radar arrays, satellite communication ground stations, and aerospace telemetry. They are equally suited for scientific research applications, such as particle accelerator RF systems, where precise waveguide positioning is essential.

​​Technical Specifications​​

The product line spans 14 models, supporting frequencies from 0.84 GHz (DH-840DRWSH) to 40 GHz (DH-180DRWSH). For example, the DH-250DRWSH operates at 2.6–7.8 GHz with a WRD250 waveguide, featuring dimensions of 22.42 mm (A) x 46.35 mm (B) x 127 mm (C/D). All units include a 12.7 mm mounting depth (E) and are finished with corrosion-resistant chromate coating. Full specifications, including CAD models (STEP/DWG), are available in the datasheet.

​​Compliance & Customization​​

Every unit undergoes Surtec 650/651 chromate conversion coating for enhanced corrosion resistance, with flanges polished to minimize RF leakage.
