Abstract

L'invention concerne un dispositif pour synchroniser un oscillateur auto-oscillant. Dans ce dispositif il est prévu un oscillateur à quartz 1 produisant le signal de référence, en série et en aval duquel sont branchés un multiplicateur et/ou un diviseur de fréquence 2, un amplificateur 3 et un filtre 7, le signal de sortie du filtre 7 est envoyé à un mélangeur d'harmoniques 4' relié à l'oscillateur auto-oscillant 4 et produisant un peigne d'harmoniques du signal de commande mfq et, par l'intermediaire de l'amplificateur sélectif 5, d'une part la fréquence intermédiaire obtenue à partir du mélangeur d'harmoniques et d'autre part un harmonique ou un sous-harmonique sélectionné pfq de l'oscillateur à quartz 1 sont envoyés au circuit de régulation par asservissement. Application notamment aux systèmes d'alimentation de porteuses dans le domaine des micro-ondes.The invention relates to a device for synchronizing a self-oscillating oscillator. In this device there is provided a quartz oscillator 1 producing the reference signal, in series and downstream of which are connected a multiplier and / or a frequency divider 2, an amplifier 3 and a filter 7, the output signal of the filter 7 is sent to a harmonic mixer 4 'connected to the self-oscillating oscillator 4 and producing a comb of harmonics of the control signal mfq and, through the intermediary of the selective amplifier 5, on the one hand the intermediate frequency obtained from the harmonic mixer and on the other hand a selected harmonic or sub-harmonic pfq of the crystal oscillator 1 are sent to the regulation circuit by servo-control. Application in particular to carrier supply systems in the microwave field.
