Description
Dual polarization waveguide probes 28EWG-T64-A1 , operating from 22.5 to 45GHz with a nominal 8dB gain and low VSWR 2.0:1 with rectangular waveguide WR28 output. The waveguide flange is FBP320(UBR320). The model 28EWG-T64-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 dual linear polarization and is designed specifically for planar and cylindrical near field measurements and calibration.
