Double Ridge Waveguide Loop Coupler

Dolph Microwave’s Double-Ridge Waveguide Loop Couplers are precision-engineered components designed for high-power RF and microwave systems, operating across full waveguide frequency bands from 0.84 GHz to 40 GHz. Utilizing a robust double-ridge waveguide architecture, these couplers deliver low insertion loss (VSWR ≤1.15:1) and precise coupling values ranging from 20 dB to 60 dB, with consistent directivity of 12–15 dB. Ideal for applications demanding high power handling and wideband performance, they are available in WRD-series waveguide sizes (e.g., WRD840 for 0.84–2.0 GHz, WRD180 for 18–40 GHz) and support coaxial interfaces like N-Type, SMA, or 2.92mm connectors.

​​Key Features​​

The couplers achieve full waveguide frequency coverage while maintaining exceptional power-handling capabilities, making them suitable for radar, satellite communications, and industrial heating systems. Their single-arm or multi-arm configurations offer flexibility for diverse signal routing needs. Constructed from corrosion-resistant aluminum or copper with Surtec-treated surfaces and chromate/painted finishes, they ensure durability in harsh operational environments.

​​Applications​​

These couplers are critical for high-frequency systems, including 5G networks, millimeter-wave radar, and microwave chemistry setups. Their pressure-sealed variants are tailored for aerospace and sealed industrial systems requiring reliable performance under extreme conditions.

​​Customization & Support​​

Dolph Microwave offers tailored solutions for unique requirements, including custom coupling values, flange designs, and finishes. All models include Surtec corrosion protection and meet industrial reliability standards.
