Classification: CPC H | IPC H

Claim 1:
2. An amplification device comprising:
a pulse signal acquisition part that acquires a desired signal that is a pulse signal to be amplified, the pulse signal acquisition part including
an input port configured to receive the desired pulse signal to be amplified, and
an output port configured to output the desired pulse signal;

a dummy signal generation part that generates a dummy signal including
an output port configured to output the generated dummy signal, and
a dummy signal generating circuit configured to
generate the dummy signal with a frequency different from the frequency of the received desired pulse signal, or generate the dummy signal with a modulation different from the modulation of the received desired pulse signal, and
generate the dummy signal with a duration such that when the dummy signal is added to the start and end of the received desired pulse signal to produce a composite signal, the power of the composite signal is constant;

a combination part that adds the dummy signal before the start of and after the end of the desired pulse signal and outputs a composite signal including
an input port configured to receive the generated dummy signal from the output port of the dummy signal generation part and to receive the desired pulse signal from the output port of the pulse signal acquisition part,
a circuit configured to add the dummy signal before the start of and after the end of the desired pulse signal to produce the composite signal, and
an output port configured to output the composite signal; and

an amplifier that amplifies the composite signal and outputs an amplified composite signal including
an input port configured to receive the composite signal from the output port of the combination part,
an amplifier circuit configured to amplify the received composite signal, and
an output port configured to output the amplified composite signal, wherein

the dummy signal is a signal that is separable from the desired pulse signal,
the power of the composite signal is a power that causes the amplification part to operate nonlinearly, and
the power of the composite signal is constant within a time range obtained by adding a predetermined time to a duration time of the desired pulse signal.
