Description
Open ended waveguide probe 28EWG-A1, operating from 26.5 to 40GHz with a nominal 6dB gain and low VSWR 1.5:1 with retangular waveguide WR28 output. The waveguide flange is FBP320(UBR320). The model 28EWG-A1 is equipped with absorber to get better gain flatness and radiation pattern performance. A small degree chamfer is utilized to give a knife-edge aperture of this model to minimize the end diffraction. This open ended waveguide probe has linear polarization and designed specifically for planar and cylindrical near field measurements and calibration.
