SAG-2533033502-315-S1

Rev. 1.1

Description:
Model SAG-2533033502-315-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 both linear and circular polarized
waveforms and employs a corrugated feed horn tooffer excellent aperture efficiency, high crosspolarization rejections, and low sidelobe levels. Thismodel is equipped with a 0.315” diameter circular
waveguide and UG-599/U flange as its input port. By adding a mode transition, SAGE Millimeter model
number SWT-28315-SB, the input port becomes a standard WR-28 waveguide, which can only support
linear polarized waveforms.
