WR-05 Waveguide Twist
The WR-05 Waveguide Twist is a precision-engineered waveguide component that rotates the polarization of the electromagnetic wave by 90 degrees. It is specifically designed for the 140 - 220 GHz frequency range, serving as a critical building block in G-Band infrastructure.
The physical waveguide tube is gradually twisted along its longitudinal axis over a distance of at least two wavelengths, smoothly rotating the E-field and H-field without causing reflection. 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
Gradual Twist Profile
Progressive twist geometry minimizes signal reflections and maintains TE10 mode integrity through the full 90-degree rotation.
Low Insertion Loss
Precision-machined interior walls ensure consistent waveguide dimensions throughout the twist length for minimal signal degradation.
Compact Design
Optimized twist length balances compact form factor with RF performance, fitting into tight waveguide assemblies without compromising signal quality.
Gold-Plated Construction
OFHC copper body with gold plating provides excellent conductivity, corrosion resistance, and consistent long-term electrical performance.

Frequently Asked Questions
Why twist the waveguide instead of just rotating the flange?+
Many complex systems (like satellite feed horns or radar gimbals) require the signal to exit at a 90-degree angle to the transmitter. Since you cannot simply bolt two rectangular flanges together at 90 degrees without completely blocking the wave, a dedicated twist component must be used.
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.
