SAF-4036031340-219-S1

WR-19 Scalar Feed Horn Antenna, 40 to 60 GHz, 13 dBi
SAF-4036031340-219-S1 is a WR-19 scalar feed horn antennaassembly that covers several popular 5G bands in the frequency rangeof 40 to 60 GHz. At center frequency, the horn antenna exhibits 13 dBi
nominal gain and a typical half power beamwidth of 40 degrees. Theantenna has a return loss of 20 dB, and -25 dB side lobe levels on the EPlane and H-Plane. The antenna is equipped with a ø0.219” circularwaveguide with a UG-383/U-M flange.

NOTE:• Gain and Return Loss data presented are collected from a sample lot. Actual data may vary unit to unit, slightly.
• Antenna patterns and 3 dB beamwidth are simulated. Actual data may vary.
••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.
Eravant reserves the right to change the information presented without notice.

CAUTION:•••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 be applied: 8.0 ± 0.15 inch-pounds(0.90 ± 0.02 Nm). Torque wrench model SCH-08008-S1 is highly recommended.
