SAQ-903017-10-S1
W-Band Spot-Focusing Lens Antenna, 1.7” Focal Length

SAQ-903017-10-S1 is a W-Band spot-focusing lens antennathat delivers a typical 10 dB spot size of 0.2” at the focal
length of 1.7” and a typical return loss of 15 dB across thefrequency range of 75 to 110 GHz. The spot-focusing lensantenna is equipped with a WR-10 waveguide with UG-387/
U-M flange as its antenna port. It supports linear polarized
waveforms.

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.
