Small signal design of a dielectric resonator stabilized oscillator
Abstract
The design of a dielectric resonator stabilized oscillator based on small signal scattering parameters is presented. A cylindrical dielectric resonator, magnetically coupled to a terminated microstrip line, is the principal element of the high Q tuning network connected to the input port of a feedback unstabilized transistor. Advantages of this configuration over the output band-stop resonator oscillator are the inhibition of the frequency tuning hysteresis phenomena and the larger tuning range. Accuracy of the design is verified by the performance of a 5430 MHz test oscillator. Tuning range, spectrum, and temperature characteristics are presented and discussed.
