SAG-2533033502-28-S1

Advanced

Description:
Model SAG-2533033502-28-S1 is a 12” Ka-Band
Gaussian antenna that operates from 25 to 30 GHz. The
Gaussian antenna delivers a 35 dBi nominal gain and 2
degree half power beamwidth. The antenna supports
linear polarized waveforms and employs a corrugatedfeed horn to offer excellent aperture efficiency, highcross polarization rejections, and low sidelobe levels.
This model is equipped with a WR-28 waveguide andUG-599/U flange as its input port. By removing themode transition, SAGE Millimeter model numberSWT-28315-SB, the input port becomes an Ø0.315” circular waveguide, which can support both linear
and circular polarized waveforms.
