Product Information
- SKU 28EWGK
Description
- Open ended waveguide Probe 28EWGK, operating from 26.5 to 40GHz with a nominal 5dB gain and low VSWR 2.0:1 with right angle coaxial 2.92mm Female output connector. The model 28EWGK has uniform gain through its frequency span, providing efficient performance characteristics and directionality. 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.
