There are different types of waveguides for different types of waves.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.• The Recommended Frequency Range corresponds to wavelength that is between 1.6 times the guide width and 1.05 times the guide width (1.25* F Cut-off to 1.9*F Cut-off This range may be extended however attenuation will increase significantly below this frequency range and higher order waveguide modes may start to propagate above it.SPECIFICATIONS:Wall Theoretical Waveguide Frequency Material Outside Thickness Ins.
