Product Information
- SKU 34EWG-A1
- Patents ZL201921371930.2 (China)
Description
- Open ended waveguide probe 34EWG-A1, operating from 22 to 33GHz with a nominal 5dB gain and low VSWR 1.8:1 with retangular waveguide WR34 output. The waveguide flange is FBP260(UBR260). The model 34EWG-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.
