WR-12 Straight Waveguide
The WR-12 Straight Waveguide is a precision-engineered waveguide component that provides ultra-low loss linear signal transmission for bridging gaps in RF systems. It is specifically designed for the 60 - 90 GHz frequency range, serving as a critical building block in E-Band infrastructure.
Straight waveguide sections are drawn or electroformed to exact tolerances, providing a pure, unperturbed environment for dominant TE10 mode propagation over fixed distances. 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
Why use a straight waveguide instead of coaxial cable?+
At millimeter-wave frequencies, coaxial cables suffer from extreme dielectric loss and radiation leakage. A hollow straight waveguide removes the center conductor and dielectric, reducing insertion loss by over 80% compared to a coax cable.
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.
