Waveguide Dimensions PDF

This page covers rectangular waveguide dimensions as per USA standard including frequency ranges, internal dimensions in inches and internal dimensions in millimeters and flange sizes for some bands. It covers standard waveguide dimensions from WR-770 to WR-0.51. This is a handy Waveguide Dimensions PDF that any engineer can use in his or her career as an mmWave engineer.

This chart is in poster size, so if you need to print is made for printing regular paper size or up to a 36″ x 47″ size in hi resolution.

Note:
• The “WR” designation stands for Rectangular Waveguides

• The Number that follows “WR” is the width of the waveguide opening in mils, divided by 10. For Example WR-650 means a waveguide whose cross section width is 6500 mils.

• The waveguide width determines the lower cutoff frequency and is equal (ideally) to ½ wavelength of the lower cutoff frequency
