Abstract
A signal generating sectionoutputs an amplitude signal and a frequency signal by conducting a signal processing on inputted data. A regulatoroutputs a signal that is proportional to a magnitude of the amplitude signal. The signal outputted from the regulatorpasses through a low pass filter, and is inputted into a power amplifier. The power amplifierconducts an amplitude modulation on a frequency signal on which an angle modulation is conducted by an angle modulation section, using a signal outputted from the low pass filter. A controlling sectioncontrols an amount of attenuation of a radio frequency component at the low pass filterbased on information such as: a modulation method of the inputted data; a modulation condition of the inputted data; a reception band; an output power of a modulation signal; and a frequency of the modulation signal.
