SAG-2533033005-28-S1

Rev. 1.0

Description:
Model SAG-2533033005-28-S1 is a 6” Ka-Band Gaussianantenna that operates from 25 to 30 GHz. The Gaussianantenna delivers a 30 dBi nominal gain and 5.0 degree
half power beamwidth. The antenna supports linear
polarized waveforms and employs a corrugated feedhorn to offer excellent aperture efficiency, high crosspolarization rejections, and low sidelobe levels. Thismodel is equipped with a standard WR-28 waveguideand UG-599/U flange as its input port. By removing the mode transition, SAGE Millimeter model number
SWT-28315-SB, the input port becomes 0.315’’ diameter circular waveguide, which can support bothlinear and circular polarized waveforms.
