The oscillator is formed by two inductors S1, S2 mounted respectively in the emitter and the base of a ultra-high-frequency transistor T1 whose collector is connected to the general positive terminal by way of a first resistor R1, the first S1 of these inductors being connected to earth by way of a variable resistor P1, whilst the other S2 is connected, on the one hand, to earth by way of a second resistor R2, and, on the other hand, to the positive terminal by way of a third resistor R3. The base-emitter junction of a second ultra-high-frequency transistor T2 is mounted in series with the second resistor R2 and a diode D2 is mounted in the bridge formed by the first and third resistor. <IMAGE> |
