The WR137 Flexible Waveguide is a 23.5-inch RF transmission line engineered for the 6.425–7.125 GHz band. Its flexible construction accommodates dynamic routing and misalignment conditions while maintaining signal integrity across demanding microwave installations. The waveguide delivers low-loss performance suitable for laboratory, field, and production environments.

– Key Features
• Flexible core design enables E-plane and H-plane bending for confined routing
• Multiple jacketing options—epoxy paint, neoprene, urethane, and UV-resistant silicone—for environmental protection
• Brass or aluminum construction with silver plating or nickel-plated flanges
• Attenuation as low as 0.05 dB/ft minimizes signal loss over moderate distances
• Minimum bend radii: 1.50–2.38 inches (E-plane, with jacket) and 2.07–3.38 inches (H-plane, with jacket)
• Repeated bending ratings available for dynamic applications
– Typical Applications
• Antenna feed systems in satellite and terrestrial RF networks
• Radar and test equipment interconnections
• Microwave transmission in confined spaces requiring flexible routing
• Laboratory and field test setups with frequent reconfiguration
– Compatibility & Integration
WR137 components connect via standard flanged interfaces. Confirm flange type and connector gender with your system architecture. Available in both jacketed and bare configurations to match thermal and mechanical requirements.
