Abstract :
The design of microwave oscillators using solid-state, negative-resistance devices is considered from the point of view of the general criterion for a steady-state free-running oscillator circuit. The intersection of the circuit admittance locus with the large-signal "device plane" - the conductance and susceptance as a function of frequency and r.f. amptitude - fully defines the operating point. A new technique for the measurement of the device admittance under oscillation conditions and the results of such a measurement for a BARITT diode will be presented. The use of the "device plane" in designing an oscillator for a given frequency and amplitude of oscillation with best stability and noise performance will be discussed.
