Abrégé
(EN)
An electronic oscillator of the Colpitts type with an amplifying element (A) and a tank circuit (T). The tank circuit (T) includes a parallel tuned resonant circuit (PT), a series tuned resonant circuit (ST) and a switching circuit (SW) that selectively connects one of the resonant circuits (PT, ST) to the tank circuit (T). The oscillator operates at a first frequency in the parallel tuned mode and a second frequency that is substantially twice the first frequency in the series tuned mode.

L'invention concerne un oscillateur électronique du type Colpitts, avec un élément amplificateur (A) et un circuit bouchon (T). Ce circuit bouchon (T) comporte un circuit résonnant accordé parallèle (PT), un circuit résonnant accordé série (ST) et un circuit de commutation (SW) qui relie sélectivement l'un des circuits résonnants (PT, ST) au circuit bouchon (T). L'oscillateur fonctionne à une première fréquence en mode accordé parallèle et à une seconde fréquence, sensiblement double à la première, en mode accordé série.
