SAG-8831044002-094-S1
W-Band Gaussian Optics Antenna, 88 to 100 GHz, 40 dBi

SAG-8831044002-094-S1 is a 6” W-Band Gaussian antenna thatoperates from 88 to 100 GHz. The Gaussian antenna delivers a40 dBi nominal gain and 1.5 degree half power beamwidth at thecenter frequency. The antenna supports linear and circular polarized
waveforms and employs a corrugated feed horn to offer excellent
aperture efficiency, high cross polarization rejections, and low
sidelobes levels. This model is equipped with a 0.094” diameter circular
waveguide and UG-387/U-M flange as its input port. By adding amode transition, Eravant model number SWT-10094-SB, the input
port becomes WR-10 waveguide, which can support linear polarizedwaveforms.

NOTE:
••
•

On condition that test data is provided it is collected from a sample lot. Actual data may vary slightly
from unit to unit. All testing is performed under +25 °C room temperature.
On condition that simulated test data is provided, actual measured data may slightly vary.
Eravant reserves the right to change the information presented without notice.

CAUTION:••••

If a waveguide is present, any foreign objects in the waveguide will cause performance degradationand may damage or destroy the unit.
Any foreign objects in the antenna will cause performance degradation and possible device
damage.
For 1 mm connectors proper torque should be applied: 4.0 ± 0.15 inch-pounds (0.45 ± 0.02 Nm).
Torque wrench model SCH-06004-S1 is highly recommended.
For 1.35 mm, 1.85 mm, 2.4 mm, 2.92 mm, and SMA connectors proper torque should beapplied: 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm). Torque wrench model SCH-08008-S1 is highly
recommended.
