Abstract
An input radio frequency signal to be amplified is fed to the gate terminals of parallel field effect power transistors through impedance matching networks that comprise parallel resistor-capacitor combinations. The capacitor is selected so that it is self-resonant at the frequency of operation, thereby preventing attenuation of the input signal at that frequency. A shunt resistor is coupled between the gates of the parallel transistors to eliminate odd mode oscillations.
