SBL-1834232840-KFKF-E3

Rev 1.3

Description:
Model SBL-1834232840-KFKF-E3 is a low noise amplifier
with a typical small signal gain of 28 dB and a nominal
noise figure of 4 dB across the frequency range of 18 to42 GHz. The DC power requirement for the amplifier is +5
VDC/210 mA. Due to the small package, the amplifier does
not have a built-in regulator. The input and output port
configurations are both female K connectors. Other port
configurations are available under different model numbers.

All data presented is collected from a sample lot. Actual data may vary unit to unit.
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.
Due to compact package size, the amplifier does not have an internal voltage regulator.
Therefore, any reverse or over bias will damage the amplifier. Never allow the bias voltage
exceeds +5.5 VDC because the amplifier will be damaged.
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.
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.
