SBL-4735232445-1919-S1

Advanced

Description:
Model SBL-4735232445-1919-S1 is a U band low noise
amplifier with a typical small signal gain of 24 dB and anominal noise figure of 4.5 dB in the frequency range of
47.0 to 51.5 GHz. The DC power requirement for theamplifier is +6 VDC/130 mA. The mechanicalconfiguration offers a right angle structure with WR-19
waveguides and UG-383/U-M flange. Other port
configurations, such as an in line structure with WR-19 waveguides or 1.85 mm connectors, are alsoavailable under different model numbers.

Note:••••All data presented is collected from a sample lot. Actual data may vary unit to unit, slightly.
All testing was performed under +25 ˚C case temperature.
SAGE Millimeter, Inc. reserves the right to change the information presented without notice.
Other mechanical configurations are available under different model numbers.

Caution:•••••Exceeding absolute maximum ratings shown will damage the device.
The device is static sensitive. Always follow ESD rules when working with the device.
The case temperature of the device shall never exceed +50 ˚C. Use proper heatsink or fan ifnecessary.
Any foreign objects in the waveguide will cause performance degradation and may damage thedevice.
Proper torque, 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm), should be applied. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
