Patent ID: 7929989

Claim:
An apparatus for RF power transmission, modulation, and amplification, comprising: a digital control module; and analog circuitry coupled to said digital control module; wherein said digital control module comprises: an input interface; an output interface; and a state machine; wherein said analog circuitry comprises: one or more circuit signal paths, each of said circuit signal paths enabling RF transmission in a respective frequency band; wherein each of said circuit signal paths comprises one or more output paths, each of said output paths enabling RF transmission according to a respective technology mode, and wherein each of said output paths includes at least one power amplification output stage, including a multiple input single output (MISO) amplifier, said MISO amplifier configured according to said respective frequency band; and a feedback path including a multiplexer that multiplexes one or more of an output power detection signal, a differential amplitude error signal, and a differential phase error signal of said MISO amplifier, and provides said multiplexed signals to said digital control module.
