SBL-4735232445-1919-E1

AdvancedDescription:
Model SBL-4735232445-1919-E1 is a U band low
noise amplifier with a typical small signal gain of
24 dB and a nominal noise figure of 4.5 dB in thefrequency range of 47.0 to 51.5 GHz. The DC
power requirement for the amplifier is +6
VDC/130 mA. The mechanical configuration offers
a in-line structure with WR-19 Uni-Guide™
waveguides. Other port configurations, such as aright angle structure with WR-19 waveguides or
1.85 mm connectors, are also available under different model numbers.

Note:•••••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, the UniGuide™, 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 a
vertical input waveguide and horizontal output waveguide configuration would be SBL4735232445-1919H-E1 instead of the default SBL-4735232445-1919-E1 which indicates verticalorientation for both input and output.
Other mechanical configurations are available under different model numbers.
SAGE Millimeter, Inc. 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.
