OSCILLATORKREDSLOEB TIL FJERNSYNSMODTAGEAPPARATER |
摘要 |
An oscillator in the collector circuit, particularly for cable-television tuners. One varactor is connected between the oscillator tuned circuit and the transistor base coupling capacitor and another in the capacitive voltage divider in the base circuit; their capacitance and that of the oscillator circuit tuning diode can be varied by the tuning voltage. This substantially extends the frequency variation range. <IMAGE> |
