SAR-1532-04-S2

WR-04 Pyramidal Horn Antenna, 15 dBi Gain
SAR-1532-04-S2 is a WR-04 pyramidal horn antenna that operates from170 GHz to 260 GHz. The antenna offers 15 dBi nominal gain and atypical half power beamwidth of 34 degrees on the E-plane and 30
degrees on the H-plane. The antenna supports linear polarized
waveforms. The input of this antenna is a WR-04 waveguide with UG387/U-M flange.

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.

This antenna is a mature product. The reasons for only providing simulated data can be found in the following

CAUTION:••••

If a waveguide is present, any foreign objects in the waveguide will cause performance degradation and may damage ordestroy 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 be applied: 8.0 ± 0.15 inch-pounds(0.90 ± 0.02 Nm). Torque wrench model SCH-08008-S1 is highly recommended.
