WR-05 E-Plane Bend
The WR-05 E-Plane Bend is a precision-engineered waveguide component that redirects millimeter-wave signals by 90 degrees in the narrow wall (E-field) plane. It is specifically designed for the 140 - 220 GHz frequency range, serving as a critical building block in G-Band infrastructure.
E-plane bends curve along the shorter dimension of the rectangular waveguide cross-section, providing vertical signal routing while maintaining phase integrity. WR-05 (G-Band, 140-220 GHz) components cross into the Terahertz gap. With an aperture of just 0.051" x 0.0255", these components are primarily used in high-end scientific radiometry and quantum computing environments.
Key Features
E-Plane Geometry
Bend follows the narrow wall (shorter dimension) of the waveguide, routing signals vertically while maintaining the broad-wall dimension.
Low Insertion Loss
Optimized bend radius and CNC-machined interior walls ensure minimal signal degradation through the 90-degree turn.
Precision CNC Machined
Each bend is machined from a solid billet of OFHC copper, maintaining tight dimensional tolerances throughout the bend radius.
Gold-Plated Construction
Gold plating provides excellent conductivity, corrosion resistance, and consistent electrical performance over the component's service life.
G-Band Use Cases
Atmospheric Science
Radiometric Earth observation
THz Imaging
High-res security scanning
Quantum Computing
Cryogenic signal routing
Deep Space
Interstellar molecule detection

Frequently Asked Questions
What is the difference between an E-plane and H-plane bend?+
An E-plane bend curves the waveguide along its narrow wall (shorter dimension), shifting the electric field vertically. An H-plane bend curves along the broad wall (wider dimension), shifting the magnetic field horizontally.
How is WR-05 used in quantum computing?+
Many quantum computers require cryogenic microwave signals to manipulate qubits. WR-05 waveguides can route ultra-high frequency control signals down into the cryogenic dilution refrigerators with lower thermal conductivity than coaxial cables.
Can you use standard flanges on WR-05?+
No. WR-05 exclusively uses precision dowel-pinned flanges (like the UG-387/U-Mod) because human hands cannot reliably align a 1.2mm wide hole visually. The precision steel pins force the microscopic apertures to align perfectly.
