ABSTRACT:
A two-stage, interstage transformer-coupled amplifier is provided with a degeneration resistor coupled between the collector of the first stage transistor and the power supply to limit the power dissipated in the first stage transistor. The first and second stages are coupled to ground through capacitor/inductor circuits to eliminate signal noise in the supply voltage. The output is filtered to remove harmonics and provide output impedance matching.
