ABSTRACT:
A gallium arsenide monolithic microwave integrated circuit amplifier comprising a first stage having a common gate field effect transistor to provide matching of the input impedance, a second stage having a common source field effect transistor to provide class A gain, and a third stage having a common source open drain field effect transistor to provide class B gain for the amplifier. This monolithic integrated circuit amplifier provides a gain of greater than 25 decibels over a frequency band of 400 Hz-1.5 GHz.
