WR-05 Waveguide Tee
The WR-05 Waveguide Tee is a precision-engineered waveguide component that splits a single millimeter-wave signal into two paths, or combines two signals together. It is specifically designed for the 140 - 220 GHz frequency range, serving as a critical building block in G-Band infrastructure.
Available in E-plane (series) or H-plane (shunt) configurations, the Tee creates a precision 3-port junction. Due to the physics of the junction, a perfect match at all three ports requires an internal matching post. 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.
Key Features

Frequently Asked Questions
What is a Magic Tee?+
A Magic Tee is a specialized 4-port component that combines an E-plane Tee and an H-plane Tee into a single unit. It acts as a 180-degree hybrid coupler, perfectly isolating the E and H ports from each other.
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.
