Abstract

PURPOSE:To set output frequencies at arbitrary frequencies, which are not limited to an integral multiple of a first reference signal, by mixing a second reference signal with the output signal of a voltage controlled oscillator, and outputting only a desired band through a voltage control band passing filter. CONSTITUTION:When the respective dividing numbers of a divider 2 and a divider 3 are made variable, in accordance with the division, the output signal of a voltage controlled oscillator 1 is set at an integral multiple of a reference signal I, the controlled output signal is mixed with the signal of a reference signal II at a mixer 6. 'output signal+reference signal II', 'output signal-reference signal II', and other frequency waves are generated to the output of the mixer 6, in such a time, when the control voltage of a voltage control band passing filter 7 is at a feedback voltage VC and is set so as to synchronize with the frequencies of 'output signal+reference signal II', the output passing through the filter 7 becomes the frequencies of 'output signal+ reference signal II' and the other frequencies are eliminated. Thus, the output signal does not limited to the integral multiple of the reference signal I, and it can be set at the arbitrary frequencies.
