Product Information
- SKU 34EWG
Description
- Open ended waveguide probe 34EWG, operating from 22 to 33GHz with a nominal 5dB gain and low VSWR 1.8:1 with retangular waveguide WR34 output. The waveguide flange is FBP260(UBR260). The model 34EWG 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.
