摘要: Embodiments of the present invention may include power amplifier architectures and systems for use in wireless communication systems. The a first circuit path receiving an input signal decomposing into two vector signals using out-phasing generator, modifying vectors based on predetermined value limit, amplifying amplifiers, combining to provide amplified output. system second generating estimate envelope modulate voltage supplies amplifiers when signals. also feedback sending information regarding which modify response thereto.
