Abstract:
Aspects of a method and system for polar modulation with discontinuous phase for RF Transmitters with power control may include performing by one or more circuits comprising a plurality of amplifiers, configuring one or more of the plurality of amplifiers to provide a coarse amplitude gain and a power level gain. One or more remaining ones of the plurality of amplifiers may be configured to provide an amplitude offset gain, and a signal may be amplified utilizing a combined gain provided by the one or more of the plurality of amplifiers and by the one or more remaining ones of the plurality of amplifiers. The signal may comprise modulated RF signal, and/or a phase modulated RF signal. An RF carrier signal may be modulated to generate the signal.
