Product Information
- SKU 4EWG
Description
-
Open ended waveguide probe 4EWG, operating from 170 to 260GHz with a nominal 6dB gain and low VSWR 1.5:1 with retangular waveguide WR4 output. The waveguide flange is APF4. The model 4EWG 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.
