A power amplification device (1) according to an exemplary embodiment of the invention includes a Doherty amplifier (10) that is adjusted to operate at a set frequency, a frequency comparator (11) that compares a supplied frequency being a frequency of an input signal RF_IN to the Doherty amplifier (10) with the set frequency, and a protection circuit (12) that sets an operating state of the Doherty amplifier (10) to inactive when the supplied frequency and the set frequency are different. It is thereby possible to protect the Doherty amplifier (10) when the input signal RF_IN with a frequency different from the set frequency is supplied.
