Abstract
Montage oscillateur-modulateur HF. Ce montage produit un signal HF modulé stable avec une source de tension variable et sans exiger une sélection critique de composants. Une tension de polarisation est fournie au transistor de l'oscillateur par des moyens comprenant au moins une diode branchée à la sortie de l'oscillateur, la tension de polarisation étant permutée sur le transistor par l'intermédiaire du circuit accordé de l'oscillateur. Avantageusement, les moyens comprenant au moins une diode polarisant un modulateur à diode connecté à la sortie de l'oscillateur et à un signal de modulation, moyennant quoi le fonctionnement linéaire du modulateur à diode est amélioré. Application particulière aux jeux vidéo.
