Patent ID: 8750414

Claim:
A method comprising: generating, from in-phase and quadrature-phase components of a modulated baseband signal, a first signal representative of an amplitude of said baseband signal and one or more second signals representative of a phase of said baseband signal; phase modulating an RF carrier signal utilizing said one or more second signals; inputting said phase modulated RF signal to a cascaded plurality of amplifiers; and configuring said cascaded plurality of amplifiers to amplitude modulate said phase modulated signal, wherein; said configuring is based on a quantized representation of said first signal; each of said plurality of amplifiers is configurable into only two configurations, a first of said two configurations comprising an amplifying configuration, and a second of said two configurations comprising a buffering configuration or a pass-through configuration; wherein the number of said cascaded plurality of amplifiers is determined based on said quantized representation of said first signal.
