Product Information
- SKU 2.8EWG
Description
- Open ended waveguide probe 2.8EWG, operating from 260.0 to 400.0GHz with a nominal 7dB gain and low VSWR 1.5:1 with rectangular waveguide WR2.8 output. The waveguide flange is APF2.8. The model 2.8EWG 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 is designed specifically for planar and cylindrical near field measurements and calibration.
