SAL-2232732212-368-S1
K-Band Lens Corrected Antenna

SAL-2232732212-368-S1 is a K-Band lens corrected antennathat operates from 22 to 27 GHz. At center frequency, theantenna delivers 22 dBi nominal gain and 12 degrees typical half
power beamwidth. The antenna employs a low loss lens to offer
excellent aperture efficiency and low sidelobes levels. The lenscorrected antenna is equipped with a 0.368” diameter circular
waveguide with UG-595/U flange as its input port. It supports
linear and circular 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.
