WR-08 H-Plane Bend
The WR-08 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 90 - 140 GHz frequency range, serving as a critical building block in F-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-08 (F-Band, 90-140 GHz) is famous for the 94 GHz atmospheric window, making it the premier choice for high-resolution cloud-mapping radar and advanced plasma diagnostics.
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.
F-Band Use Cases
Cloud Radar
94 GHz weather mapping
Plasma Diagnostics
Fusion reactor monitoring
Sub-THz Research
Advanced materials science

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.
What is the 94 GHz atmospheric window?+
While mmWave frequencies generally suffer from high atmospheric attenuation, there is a natural "window" at exactly 94 GHz where attenuation drops significantly. WR-08 components are used to build 94 GHz cloud radars that can see through fog and map weather patterns with incredible resolution.
How are WR-08 components manufactured?+
The internal dimensions of WR-08 are 0.080" x 0.040" (about 2mm x 1mm). They cannot be easily cast. They are typically electroformed (growing copper chemically over an aluminum mandrel) or precision-machined using specialized micro-milling bits to ensure perfect geometry.
