WR-28 Waveguide Tee
The WR-28 Waveguide Tee is a precision-engineered three-port junction designed for splitting or combining millimeter-wave signals operating within the 26.5 GHz - 40 GHz frequency range, commonly associated with the Ka-Band.
Available in both E-plane (series) and H-plane (shunt) configurations, this tee junction provides controlled signal distribution with predictable power division and phase characteristics. The E-plane tee produces 180-degree out-of-phase outputs, while the H-plane tee produces in-phase outputs. Constructed from OFHC copper with gold plating for minimal insertion loss and reliable long-term performance.

Frequently Asked Questions
What is a WR-28 waveguide tee?+
A WR-28 waveguide tee is a three-port junction device operating in the Ka-Band frequency range of 26.5 GHz - 40 GHz. It connects three waveguide sections at a T-shaped intersection, allowing engineers to split a signal from one port into two outputs, or combine two signals into one. Available in E-plane (series) and H-plane (shunt) configurations.
What is the difference between E-plane and H-plane tee configurations?+
An E-plane tee (series tee) has its branch arm extending from the narrow wall of the waveguide, in the direction of the electric field. The two output signals are 180 degrees out of phase. An H-plane tee (shunt tee) has its branch arm extending from the broad wall, in the direction of the magnetic field, producing two in-phase output signals.
What materials are used in RF Essentials WR-28 waveguide tees?+
RF Essentials WR-28 waveguide tees are manufactured from oxygen-free high-conductivity (OFHC) copper for the waveguide body with precision-machined brass UG-599/U flanges on all three ports. All surfaces receive gold plating for superior corrosion resistance and consistent electrical performance across the full Ka-Band operating range.
