SAG-1441544601-06-S1

Rev. 1.3

Description:
Model SAG-1441544601-06-S1 is a 6” D-Band Gaussianantenna that operates from 140 to 150 GHz. The Gaussianantenna delivers a 46 dBi nominal gain and 0.95 degree
half power beamwidth. The antenna supports linear
polarized waveforms and employs a corrugated feed horn
to offer excellent aperture efficiency, high crosspolarization rejections, and low sidelobe levels. Thismodel is equipped with a standard WR-06 waveguide andUG-387/U-M flange as its input port. By removing themode transition, Eravant model number SWT-06059-SB,
the input port becomes a 0.059” diameter circular waveguide, which can support both linear andcircular polarized waveforms.
