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 cryogenic test 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 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.
