Dynamic Behavior of Nonlinear Power Amplifiers in Stable and Injection-Locked Modes

Dynamic equations of reflection-type nonlinear power amplifiers in both stable and injection-locked modes are derived for modulated signals. The steady-state response and the transient response of an injection-locked negative-resistance diode ampfitier is evaluated. The response for an FM signal is discussed. Numerical results show that the dynamic behavior as well as the steady-state behavior is affected by nonlinearity of the diode conductance and susceptance.
