    Abstract: PURPOSE:To obtain plural precise and stable oscillation frequency by setting the bias of an oscillation transistor (TR) to the optimum oscillation conditions of respective crystal oscillators and using the setting resistor also as a selecting resistor for a crystal oscillator to be required. CONSTITUTION:When a changeover switch 1 is turned to the earth side, a switching TR3 is turned off, a switching diode 10 is forwardly biased by resistors 4, 6, 11 and the other switching diode 9 is reversely biased to select a crystal oscillator 8. Simultaneously, the bias voltage of an oscillation TR14 is determined by the resistors 4, 6, 11 and the diode 10. When the changeover switch 1 is turned to the power supply side on the other hand, the switching diode 9 is forwardly biased by the resistors 5, 11 and the switching diode 10 is reversely biased to select a crystal oscillator 7. Consequently, the bias voltage of the oscillation TR14 is determined by the resistors 5, 11 and the diode 9.

    Abstract: The oscillator having a tunable resonant circuit has a switch for expanding the tuning range, which is connected in series with two coils jointly determining the oscillation frequency of the resonant circuit. A further coil, which is coupled to the resonant circuit in the region of the switch, is used to supply a switching voltage for the switch. In this arrangement, the other end of this third coil is coupled to a reference potential, with a capacitor, which acts as a short circuit for radio-frequency purposes, decoupling the switching voltage from the reference potential. Since the switching voltage is in this case coupled to an oscillator circuit node which is earthed for radio-frequency purposes, it is of no significance in this case which resistor is used to couple the switching voltage. This means that the resonant circuit is not resistively damped by the connection of the switching voltage. Coupled to the other end of the switching diode is a further component, preferably a fourth coil, which has the same inductance as the third coil, in order to dissipate the switching voltage. The first two coils are advantageously of the same size, so that this circuit coil jointly determining the oscillation frequency is earthed by the third coil exactly at its center. This means that the quality factor and the oscillation properties of the resonant circuit are not adversely affected.

    Abstract: In a voltage controlled oscillator in which an operation frequency is determined by applying a tuning voltage to a resonant circuit connected to a control terminal of a transistor (T1), the resonant circuit has zeroth and first varactor diodes (D0, D1) which can serve as capacitance elements. A selection voltage is applied to an anode of the first varactor diode through a band selection terminal (1). The first vatactor diode has a capacitance varying in response to the value of the selection voltage. The variation of the capacitance causes a change of a frequency band of the voltage controlled oscillator. A tuning voltage is applied through a tuning terminal (2).
