Frequently Asked Questions
What is a WR-28 waveguide?+
A WR-28 waveguide is a rectangular waveguide with internal dimensions of 0.280 x 0.140 inches, designed for guided electromagnetic wave transmission in the Ka-band frequency range of 26.5 GHz to 40 GHz. The WR-28 designation follows the EIA standard where 28 represents the broad wall dimension in hundredths of an inch.
What frequency range does the WR-28 waveguide cover?+
The WR-28 waveguide covers 26.5 GHz to 40 GHz, which falls within the Ka-band. This frequency range is used in 5G backhaul, satellite communications, military radar, and high-resolution imaging systems.
What materials are used in RF Essentials WR-28 waveguides?+
RF Essentials WR-28 waveguides are manufactured from oxygen-free high-conductivity (OFHC) copper for the waveguide body and precision-machined brass for the UG-599/U flanges. A gold plating finish is applied to all surfaces for corrosion resistance and optimal electrical conductivity.
