Product Information
- SKU 137EWGES
Description
- Open ended waveguide Probe 137EWGES, operating from 5.85 to 8.2GHz with a nominal 5dB gain and low VSWR 2.0:1 with endlaunch coaxial SMA Female output connector. The model 137EWGES 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.
