Abstract
There is provided a power amplifier capable of readily reducing odd-order harmonic waves even in high frequencies. This power amplifier includes n current sources (where 'n' is a natural number equal to or greater than 3) that cause predetermined currents to flow; n switches that open and close current paths of the n current sources, respectively; and a signal generating section that generates n timing signals for turning on/off the n switches, respectively. In the power amplifier, the n timing signals are signals that have an identical duty ratio and that are different in phase; and the power amplifier outputs a signal amplified in power based on the currents flowing through the n current sources.
