WR-05 H-Plane Bend
The WR-05 H-Plane Bend is a precision-engineered waveguide component that redirects millimeter-wave signals by 90 degrees in the broad wall (H-field) plane. It is specifically designed for the 140 - 220 GHz frequency range, serving as a critical building block in G-Band infrastructure.
H-plane bends curve along the wider dimension of the rectangular waveguide cross-section, providing horizontal signal routing without inducing higher-order modes. 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 cryogenic test environments.
Key Features
H-Plane Geometry
Bend follows the broad wall (wider dimension) of the waveguide, routing signals horizontally while maintaining the narrow-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
Cryogenic Test
Low-heat-load signal routing

Frequently Asked Questions
Why use an H-plane bend over an E-plane bend?+
H-plane bends are used when the signal needs to be routed horizontally across an optical table or chassis without twisting the polarization of the wave. The wider bend radius typically handles higher peak power than an E-plane bend.
How does WR-05 perform in cryogenic systems?+
Waveguide carries far less heat down a cold chain than coaxial cable of equivalent bandwidth. WR-05 can route G-band signals into a cryostat while limiting the thermal load reaching the cold stage, which is why thin-wall waveguide runs are common in low-temperature test setups.
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.
