STB-1834034030-KFKF-L1

Rev 1.0

Description:
Model STB-1834034030-KFKF-L1 is a broadband benchtop
low noise amplifier with a typical small signal gain of 40 dB
and a nominal noise figure of 3 dB across the frequency rangeof 18 to 40 GHz. The power supply required is a single phase
AC voltage in the range of 100 to 240 VAC, which can besupplied by a wall outlet. The LED light helps to indicate theworking status of the amplifier. The input and output port
configurations are female K connectors.
