WR-05 High Power Termination
The WR-05 High Power Termination is a precision-engineered waveguide component that absorbs massive amounts of RF energy, safely dissipating it as heat to prevent signal reflection. It is specifically designed for the 140 - 220 GHz frequency range, serving as a critical building block in G-Band infrastructure.
High-power terminations feature a wedge-shaped ceramic or silicon-carbide absorbing element bonded to a large external heatsink with cooling fins to maximize thermal convection. 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
What happens if a high power termination overheats?+
If the absorbing wedge exceeds its thermal limit, it can crack or outgas. More importantly, as it heats up, its electrical resistance changes, ruining the impedance match and causing massive RF reflections (high VSWR) back into your amplifier.
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.
