Abstract
Burnout resistance ferroelectric material is used in the feedback path of a microwave oscillator as a frequency control element. The ferractor has rapid broadband frequency tuning capabilities limited only by the speed of an external DC source.
Claims10
A voltage tuned ferroelectric resonant microwave oscillator, which comprises:
- amplifier means for providing voltage gain to a RF output port of said oscillator;
- power split means for providing a feedback loop to said amplifier means and an electrical connection to said RF outport;
- ferroelectric resonator means operatively positioned in said feedback loop for providing broad band voltage tuning of said oscillator;
- input network means operatively coupled intermediate said resonator means and said amplifier means for minimizing impedance mismatch between said resonator means and said amplifier means;
- output network means operatively coupled intermediate said power split means and said amplifier means for minimizing impedance mismatch between said power split means and said amplifier means;
- and
- ferroelectric voltage driver means for providing a DC biasing voltage for said resonator means.
