Abstract
A wireless communication device includes a delay circuit to generate four or more delay signals, an amplifier circuit amplifying the four or more delay signals to generate four or more amplified delay signals, and a combiner circuit combining at least two amplified delay signals to generate an output signal, a second phase of a second amplified delay signal is between a first phase of a first amplified delay signal and a third phase of a third amplified delay signal, gains of the amplifier circuit for the four or more delay signals are controlled such that the output signal is generated by combining the first amplified delay signal and the third amplified delay signal, and a phase of the output signal is between the first phase of the first amplified delay signal and the third phase of the third amplified delay signal.
