SBL-3333734030-28KF-E1

AdvancedDescription:
Model SBL-3333734030-28KF-E1 is a low noise amplifier
with a typical small signal gain of 40 dB and a nominal
noise figure of 3 dB across the frequency range of 33 to37 GHz. The DC power requirement for the amplifier is+8 VDC/205 mA. The mechanical configuration is an inline
structure with WR-28 Uni-Guide™ waveguide as its input
port and K(F) connector as its output port. Other port
configurations, such as K connectors and WR-28 waveguides for either the input or output port, are alsoavailable 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.
The amplifier employs SAGE Millimeter’s trademarked and patent pending technology, UniGuideTM, as its waveguide interfaces. The orientation of the input and the output waveguides
can be specified through corresponding model numbers. For example, the model number for ahorizontal input waveguide configuration would be SBL-3333734030-28HKF-E1 instead of thedefault SBL-3333734030-28KF-E1 which indicates vertical orientation input.
Other mechanical configurations are available under different model numbers.
Eravant reserves the right to change the information presented without notice.

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. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
