ABSTRACT:
Aspects of a method and system for polar modulation with discontinuous phase for RF transmitters with integrated amplitude shaping may include amplifying a signal via a plurality of amplifiers such that a combined gain of the plurality of amplifiers comprises a coarse amplitude gain, an amplitude offset gain and a pulse-shaping gain. A gain of one or more of the plurality of amplifiers may be adjusted to set the coarse amplitude gain. A gain of one or more of the plurality of amplifiers may be adjusted to set the amplitude offset gain and the pulse-shaping gain, wherein the one or more of the plurality of amplifiers used to set said amplitude offset gain and said pulse-shaping gain are distinct from the one or more of said plurality of amplifiers used to set the coarse amplitude gain.
