WR-12 Low Power Termination
The WR-12 Low Power Termination is a precision-engineered waveguide component that provides an exact precision match for terminating unused ports during VNA calibration and testing. It is specifically designed for the 60 - 90 GHz frequency range, serving as a critical building block in E-Band infrastructure.
Low-power terminations prioritize absolute minimum VSWR over heat dissipation, using a highly engineered, delicate absorbing element designed for milliwatt-level measurement accuracy. 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
Can a low power termination be used for calibration?+
Yes. Low power terminations are frequently used as the "Load" standard during a Short-Short-Load-Thru (SSLT) calibration on a Vector Network Analyzer, requiring them to have near-perfect return loss (better than 30 dB).
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.
