Frequently Asked Questions
What is a WR-22 waveguide?+
A WR-22 waveguide is a rectangular waveguide with internal dimensions of 0.224 x 0.112 inches, designed for guided electromagnetic wave transmission in the Q-band frequency range of 33 GHz to 50 GHz. The WR-22 designation follows the EIA standard where 22 represents the broad wall dimension in hundredths of an inch.
What frequency range does the WR-22 waveguide cover?+
The WR-22 waveguide covers 33 GHz to 50 GHz, which falls within the Q-band. This frequency range is used in point-to-point communications, radar systems, radio astronomy, and automotive radar applications.
What materials are used in RF Essentials WR-22 waveguides?+
RF Essentials WR-22 waveguides are manufactured from oxygen-free high-conductivity (OFHC) copper for the waveguide body and precision-machined brass for the UG-383/U flanges. Gold plating is applied to all surfaces for corrosion resistance and optimal electrical conductivity.
