SAG-8831044801-10-S1

W-Band Gaussian Optics Antenna, 88 to 100 GHz, 12”
Lens
SAG-8831044801-10-S1 is a 12” W-band Gaussian antenna thatoperates from 88 to 100 GHz. The Gaussian antenna delivers a 48 dBi
nominal gain and 0.8 degree half power beamwidth. The antenna
supports linear polarized waveforms and employs a corrugated feed horn
to offer excellent aperture efficiency, high cross polarization rejections,and low sidelobe levels. This model is equipped with a standard WR-10
waveguide and UG-387/U-M flange as its input port. By removing themode transition, SAGE Millimeter model number SWT-10094-SB, theinput port becomes a 0.094” diameter circular waveguide, which cansupport both linear and circular polarized waveforms..
