SAG-8831044801-094-S1

Rev. 1.3

Description:
Model SAG-8831044801-094-S1 is a 12” W-band Gaussianantenna that operates from 88 to 100 GHz. The Gaussianantenna delivers a 48 dBi nominal gain and 0.8 degree half
power beamwidth. The antenna supports both linear andcircular polarized waveforms and employs a corrugatedfeed horn to offer excellent aperture efficiency, high crosspolarization rejections, and low sidelobe levels. This model
is equipped with a 0.094” diameter circular waveguide andUG-387/U-M anti-cocking flange as its input port. By
adding a mode transition, Eravant model number SWT-10094-SB, the input port becomes a standard
WR-10 waveguide, which can only support linear polarized waveforms.

Note:• Eravant reserves the right to change the information presented without notice.
• The operation frequency of the antenna can be extended to a wider range with small
performance degradation at the edges of the band.
Caution:• Foreign objects in the waveguide will affect the antenna performance and may damage theantenna.
