Abstract
In a device for use in processing a baseband input signal and a carrier signal into an envelope output signal, a processing unit (3) is supplied with the baseband input signal and the carrier signal and produces, as a produced signal, a modulated signal and a non-modulated signal one at a time in response to a burst control signal. A waveform generating unit (2) is supplied with the burst control signal and generates a control signal. An amplifying unit (4) is supplied with the produced signal and the control signal and amplifies the produced signal to make the envelope output signal represent an envelope of the produced signal and to produce the envelope output signal with an excellent spectrum suppression. Alternatively, the processing unit may be supplied with the control signal instead of the burst control signal.
