SBL-2634033030-KF28-E1

Rev 1.0

Description:
Model SBL-2634033030-KF28-E1 is Ka band low
noise amplifier with a typical small signal gain of 30
dB and a nominal noise figure of 3.0 dB across thefrequency range of 26.5 to 40 GHz. The DC power
requirement for the amplifier is +8 VDC/150 mA. The
mechanical configuration is an inline structure withK(F) connector as its input port and a WR-28 UniGuide™ waveguide 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 output waveguide configuration would be SBL-2634033030-KF28H-E1 instead of thedefault SBL-2634033030-KF28-E1 which indicates vertical orientation 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.
The case temperature of the device shall never exceed +50 ˚C. Use proper heatsink or fan if
necessary.
Any foreign objects in the waveguide will cause performance degradation and may damage thedevice.
