SBL-3333733640-2828-S1-K

Rev 1.0

Description:
Model SBL-3333733640-2828-S1-K is a low noise amplifier with atypical small signal gain of 36 dB and a nominal noise figure of 4 dB
across the frequency range of 33 to 37 GHz. The DC power requirement
for the amplifier is +8 VDC/150 mA. The input and output port
configurations are both WR-28 waveguides. Other port configurations,such as K connectors or WR-28 waveguides for either the input oroutput port, are also available under different model numbers.
