WR-12 Waveguide Tee
The WR-12 Waveguide Tee is a precision-engineered waveguide component that splits a single millimeter-wave signal into two paths, or combines two signals together. It is specifically designed for the 60 - 90 GHz frequency range, serving as a critical building block in E-Band infrastructure.
Available in E-plane (series) or H-plane (shunt) configurations, the Tee creates a precision 3-port junction. Due to the physics of the junction, a perfect match at all three ports requires an internal matching post. 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
What is a Magic Tee?+
A Magic Tee is a specialized 4-port component that combines an E-plane Tee and an H-plane Tee into a single unit. It acts as a 180-degree hybrid coupler, perfectly isolating the E and H ports from each other.
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.
