摘要：A quadrature modulator divides a first signal input as a local signal into an Ichannel signal and a Q channel signal orthogonal to each other and outputs a secondsignal having a desired phase delay corresponding to direct current voltages as for thefirst signal by giving the direct current voltages Vi and Vq to the I channel signal and theQ channel signal, respectively. A phase comparison unit detects a phase difference θbetween the first signal and the second signal. A setting unit sets the desired phasedelay. A controller section controls the direct current voltages supplied to the I channelsignal and the Q channel signal respectively in the quadrature modulator so that anoutput value corresponding to the phase difference θ detected by the phase comparisonunit is equal to a value corresponding to the desired phase delay set by the setting unit,and controls the direct current voltages to be the direct current voltages Vi and Vqsatisfying the relation of Vi = cosθ and Vq = sinθ.
