Agilent 87405A Preamplifier, 10 MHz to 3 GHz

The 87405A Preamplifier is a multi-purpose instrument for any application that requires low noise and additional gain. The SNR of the final signal in an RF system is greatly impacted by the initial amplification of the signal and its original SNR. By having low noise figure in a preamplifier, the final signal will have a lower noise than without the preamplifier.
