STB-1832735025-KF2F-L1

AdvancedDescription:
Model STB-1832735025-KF2F-L1 is a broadband benchtop
low noise amplifier with a typical small signal gain of 50 dB
and a nominal noise figure of 2.5 dB across the frequency
range of 18 to 26.5 GHz. The power supply required is a single
phase AC voltage in the range of 100 to 240 VAC, which can besupplied by wall outlet. The LED light helps to indicate theworking status of the amplifier. The input connector is 2.92mm (F) connector and the output is a 2.4mm (F) connector.
