PURPOSE:To reduce the spurious component by connecting a distributer to an output of a voltage controlled oscillator, using one output as an oscillation output and connecting an amplifier and an attenuator between the other output and a mixer input. CONSTITUTION:The titled oscillator is a phase locked oscillator with less spurious oscillation provided with a mixer, in which a distributer 9 is connected to the output terminal of the voltage controlled oscillator 1, an output is extracted from one output terminal 8 and an amplifier 10 and an attenuator 11 are connected between the other output terminal and one input (RF input) of the mixer 2. Thus, since the path of spurious oscillation is provided with the attenuator 11, the amplifier 10 and the distributer 9 in addition to the mixer 2, an output with the spurious component reduced therefrom is extracted by the respective isolation effect. |
