Abstract: PURPOSE: A finely adjustable vector modulator is provided to improve the quality of adjustment regardless of noises by reducing the change of gains according to the change of a main controlling voltage. CONSTITUTION: A signal separating part(11) separates an input signal into two signals with different phases. A first gain adjuster(12) adjusts either of the gains of the signals. A first controlling voltage generator(13) distributes one main controlling voltage and generates the gain controlling voltage of attenuators included in the first gain adjuster. A second gain adjuster(14) adjusts the gain of the remained signal. A second controlling voltage generator(15) distributes one main controlling voltage inputted from the outside and generates the gain controlling voltage of attenuators included in the second gain adjuster.
