MIKROWELLEN-OSZILLATOR MIT STABILISIERUNG DURCH EINEN DIELEKTRISCHEN RESANATOR.

摘要

The dielectric resonator (2) is tuned via a tuning device (8) acting on its external electric or magnetic field. Further temp. stabilisation of the oscillator frequency is effected by dynamic adjustment of the distance of the tuning device (8) from the dielectric resonator (2), via an electromechanical transducer (7) inserted in a phase regulating loop. The latter incorporates a directional coupler (3), a frequency divider, a phase comparator and the electromechanical transducer (7), controlled by the difference between the oscillator output (A) and a reference signal provided by a reference oscillator (5).
