A device for automatic tuning of a resonator and synthesizer using such a device

摘要

P the present invention relates to devices for tuning frequency oscillators controlled electronically. It consists in adding an automatic tuning device which, in the example described, is a dielectric, which is immersed in the resonator of oscillator, mechanically coupled to an electric motor controlled by signals indicating the position of the control voltage with respect to a preferred range of operation. This arrangement makes it possible to combine a high spectral purity to a wide tuning band and a high resolution, as well as to maintain a locking of the servo-control loop regardless of the drifts. / p & & p & the invention applies to the frequency synthesizers with variable pitch, commonly referred to as to servo-control loop. / p
