WR-12 Medium Power Termination
The WR-12 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 60 - 90 GHz frequency range, serving as a critical building block in E-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. Operating in the 60-90 GHz E-Band, WR-12 is the backbone of modern 71-86 GHz high-capacity telecom links. The tiny 0.122" x 0.061" aperture requires anti-cocking flanges to prevent catastrophic misalignment.

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.
Why is WR-12 critical for telecom backhaul?+
The FCC opened the 71-76 GHz and 81-86 GHz bands for ultra-high-capacity point-to-point microwave links. WR-12 components are the physical standard for routing these E-Band signals from the transceiver to the parabolic dish, enabling 10+ Gbps data rates where fiber is too expensive to lay.
What is an anti-cocking flange on WR-12?+
At E-Band frequencies, if a flange is bolted together unevenly (cocked), the microscopic gap will leak massive amounts of RF energy and ruin the VSWR. Anti-cocking flanges have an outer rim that guarantees the mating surfaces remain perfectly parallel during tightening.
