Description
Dual polarization waveguide probes 28EWGK-T64-A1, operating from 22.5 to 45GHz with a nominal 8dB gain and low VSWR 2.0:1 with right angle Coaxial 2.92mm Female connector on each output. The model 28EWGK-T64-A1 is equipped with absorber for better gain flatness and radiation pattern. 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.
