SAG-1441544002-06-S1

Rev. 1.2

Description:
Model SAG-1441544002-06-S1 is a 3” D-Band Gaussian antennathat operates from 140 to 150 GHz. The Gaussian antennadelivers a 40 dBi nominal gain and 1.9 degree half power
beamwidth. The antenna supports linear polarized waveforms
and employs a corrugated feed horn to offer excellent aperture
efficiency, high cross polarization rejections, and low sidelobe
levels. This model is equipped with a standard WR-06
waveguide and UG-387/U-M anti-cocking flange as its input
port. By removing the mode transition, Eravant model number
SWT-06059-SB, the input port becomes a 0.059” diameter circular waveguide, which can support bothlinear and circular polarized waveforms.
