Abstract

Effects of package inductance and package capacitance on the behavior of microwave Gunn oscillator have been studied analytically and through numerical simulation. In the presence of package parasites the system equation is described by two coupled second order differential equations. Critical examination reveals that for a certain range of magnitudes of the package parasites relative to other device and circuit parameters the system dynamics can become chaotic. However, by the application of an external synchronizing signal of suitable frequency and power, the chaotic dynamics of the oscillator can be controlled. Results of numerical simulation closely agree with the analytical findings.
