Description
Open ended waveguide probe 42EWG-A1, operating from 18 to 26.5GHz with a nominal 5dB gain and low VSWR 1.8:1 with retangular waveguide WR42 output. The waveguide flange is FBP220(UBR220). The model 42EWG-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.
