A Design Method for Parallel Feedback Dielectric Resonator Oscillators

A method is proposed for the design of parallel feedback DR oscillators where output power, frequency stability and other basic performance parameters are simultaneously taken as design objectives. After introducing suitable performance indexes which define the stability and self-starting capability of the oscillator, an efficient procedure aimed at searching for the optimal compromise between opposing design requirements is described. The method has been validated by considering, as a design example, a microstrip DR oscillator using a medium power GaAs MESFET.
