SAM-2432432212-KF-L1
K-Band Microstrip Patch Array Antenna, 12° x 12°

SAM-2432432212-KF-L1 is a linear polarized, 24 GHz
microstrip patch array antenna. The antenna impements aseries-fed power distribution to achieve low sidelobe levels.
The antenna has a gain of 22 dBi and a beamwidth of 12degrees both vertically and horizontally, with a better than -20
dB sidelobe suppression level. The antenna is constructed witha high performing, low loss soft microwave substrate to achieve
the best performance in the class. The RF interface is a K (F)connector. A standard WR-42 waveguide version with a UG595/U flange is offered under model number SAM-243243221242-L1.

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.
