Abstract:
1. A transmitter for transmitting information in a modulated signal at least in a first carrier frequency band or a second, different carrier frequency band, said transmitter comprising: a signal processor for providing baseband data indicative of the information, an envelope waveform providing module, responsive to the baseband data, for providing an envelope waveform indicative of an envelope of the modulated signal, by a phase modulating mechanism for providing a first signal in the first carrier frequency band and a second signal in the second carrier frequency band, a first amplification device, responsive to the envelope waveform and the first signal, for providing the modulated signal in the first carrier frequency band, a second amplification device, responsive to the envelope waveform and the second signal, for providing the modulated signal in the second carrier frequency band, and a band selection mechanism for selecting at least between the modulated signal in the first carrier frequency band and the modulated signal in the second carrier frequency band for transmission.
