WR-05 Straight Waveguide
The WR-5 Straight Waveguide is a precision-engineered waveguide component that provides ultra-low loss linear signal transmission for bridging gaps in RF systems. It is specifically designed for the 140 - 220 GHz frequency range, serving as a critical building block in G-Band infrastructure.
Straight waveguide sections are drawn or electroformed to exact tolerances, providing a pure, unperturbed environment for dominant TE10 mode propagation over fixed distances. 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.

Frequently Asked Questions
Why use a straight waveguide instead of coaxial cable?+
At millimeter-wave frequencies, coaxial cables suffer from extreme dielectric loss and radiation leakage. A hollow straight waveguide removes the center conductor and dielectric, reducing insertion loss by over 80% compared to a coax cable.
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.
