Final Rev 1.4 SAQ-103039-90-S1 X-Band Spot-Focusing Lens Antenna, 10.3 GHz, 3.94” Focal Length SAQ-103039-90-S1 is an X-Band spot-focusing lens antenna that delivers a nominal 3 dB spot size of 1.02” at the focal length of 3.94”, and a typical return loss of 15 dB across the frequency range of 8.2 to 12.4 GHz. The antenna employs a low loss lens to offer excellent aperture efficiency at 10.3 GHz. The spot-focusing lens antenna is equipped with a WR-90 waveguide with UG-39/U flange as its antenna port. It supports linear polarized waveforms.

- 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.
- If a waveguide is present, any foreign objects in the waveguide will cause performance degradation and may damage or destroy the unit.
- Any foreign objects in the antenna will cause performance degradation and possible device damage. 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 recommended.
