Modulated signal generating device and wireless device

A wireless device comprising:

• a signal generating unit that generates a transmission signal from transmission data;
• a modulating unit that modulates the transmission signal and generates a first modulated signal;
• a modulated signal generating device that modulates the first modulated signal and generates a second modulated signal;
• and
• an antenna unit that transmits the second modulated signal, wherein
• the modulated signal generating device includes:
• a first control unit that generates a first control signal based on a first component signal included in the first modulated signal;
• a first filter that eliminates harmonic component included in a first difference signal, which represents difference between the first modulated signal and the first component signal, and generates a first filtered signal;
• a second control unit that generates a second control signal based on a second component signal included in the first modulated signal;
• a first amplifier that generates a first amplified signal based on the first control signal;
• a second amplifier that has a smaller amplification factor as compared to the first amplifier and that generates a second amplified signal based on the second control signal;
• a p-th amplifier (wherein p=3 to N, and N represents an integer equal to or greater than three) that has a smaller amplification factor than a p−1-th amplifier and that generates a p-th amplified signal based on a p-th control signal;
• a p−1-th filter that eliminates harmonic component included in a p−1-th difference signal, which represents difference between a p−2-th component signal and a p−1-th component signal, and generates a p-th component signal;
• a p-th control unit that generates the p-th control signal based on the p-th component signal;
• and
• a combiner that combines the first amplified signal, the second amplified signal, and the p-th amplified signal to generate the second modulated signal;
• wherein the p-th amplifier is plural in number, a plurality of the p-th amplifier is connected to each other in parallel, and each generates the p-th amplified signal, and the p-th control unit includes a p-th control signal generating unit that decides the p-th amplifier to be actuated from among a plurality of the p-th amplifier based on order of priority different for each predetermined interval and generates the p-th control signal for actuating the decided p-th amplifier.
