1. 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;

    a plurality of transmission paths, each of said transmission paths enabling RF transmission in a respective frequency band;

    wherein each of said transmission paths comprises a plurality of output paths, each of said output paths enabling RF transmission according to a respective technology mode; and

    a receiver-based feedback path, including a receiver that receives an active output of one of said output paths, generates in-phase (I) and quadrature-phase (Q) information from said active output, and provides said I and Q information to said digital control module, wherein said receiver-based feedback path includes a first band path and a second band path, each of said first band path and second band path including an automatic gain controller, I and Q sample-and-hold circuitry, and switching circuitry.
