Abstract
A first phase adjuster adjusts the phase of any one of first and second AC voltages generated in a negative resistance circuit so that a shift amount Φ in a first variable phase shifter falls within a range of 0 degrees≤Φ<180 degrees, and outputs the phase-adjusted AC voltage to the first variable phase shifter, and a second phase adjuster adjusts the phase of the other one of the first and second AC voltages generated in the negative resistance circuit so that a shift amount Φ in a second variable phase shifter falls within a range of 0 degrees≤Φ<180 degrees, and outputs the phase-adjusted AC voltage to the second variable phase shifter.
