Abstract:
A phase shifter includes controlling a phase of an output signal of an orthogonal modulator; and interchanging two kinds of signals inputted to the orthogonal modulator, interchanging each polarity of the two kinds of signals inputted to the orthogonal modulator, or interchanging both of the above. The two kinds of signals inputted to the orthogonal modulator are two pairs of differential signals.
