Product Information
- SKU 34EWGEK-A1
- Patents ZL201921371930.2 (China)
Description
- Open ended waveguide Probe 34EWGEK-A1, operating from 22 to 33GHz with a nominal 5dB gain and low VSWR 2.0:1 with endlaunch coaxial 2.92mm Female output connector. The model 34EWGEK-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 linear polarization and designed specifically for planar and cylindrical near field measurements and calibration.
