Abstract:
1. A method of generating a first drive signal and a second drive signal to provide a modulated radio frequency (RF) signal, the method comprising: receiving at least phase modulation (PM) information and amplitude modulation (AM) information; generating an unmodulated carrier signal; phase modulating the unmodulated carrier signal according to the phase modulation information and the amplitude modulation information with a first phase variation to provide a first drive signal; and phase modulating the unmodulated carrier signal according to the phase modulation information and the amplitude modulation information with a second phase variation to provide a second drive signal, the first and second phase variations being different, a difference in phase between the first and second drive signals associated with the amplitude modulation information, a load being driven with the first and second drive signals resulting in a modulated RF signal being phase modulated according to the phase modulation information and amplitude modulated according to the amplitude modulation information.
