WR-05 Medium Power Termination
The WR-05 Medium Power Termination is a precision-engineered waveguide component that absorbs moderate RF energy, providing a perfect 50-ohm (normalized) match to prevent reflections. It is specifically designed for the 140 - 220 GHz frequency range, serving as a critical building block in G-Band infrastructure.
Medium-power terminations utilize a precision-tapered lossy dielectric wedge that gradually absorbs the RF wave over several wavelengths, preventing any sudden impedance steps. 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
How is VSWR minimized in a termination?+
The absorbing element is machined into a sharp spear or wedge shape. When the RF wave hits the tip, it sees almost empty space. As it travels deeper, the wedge gets thicker, gradually absorbing the power so no distinct "wall" ever bounces the signal back.
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.
