Abstract

PURPOSE:To invert the output phase fluctuation due to the fluctuation of frequency, by obtaining a signal of a frequency equal to that of a carrier wave from an input carrier wave and a double frequency and converting the signal into a signal of the said double frequency through a filter and the multiplication. CONSTITUTION:The input carrier wave (a) of frequency omegaO is fed to an input terminal of one side of a frequency converter 12, and the carrier wave signal (d) of a double frequency 2omegaO is fed to an input terminal of the other side. Thus an output signal (e) of the frequency omegaO equal to the wave (a) obtained. The signal (e) is made to pass through a band pass filter 11 having the passing center frequency omegaO to prevent a higher harmonic wave. The output carrier vave C of the filter 11 is branched. A part of the branched carrier waves is fed to a multiplying circuit 13, and the output of the circuit 13 is made to pass through a pase shifter 14 and supplied to the converter 12 in the form of a carrier wave signal (d) of the frequency 2omegaO.
