Claim:
1. A system comprising: a multi-band multi-order power amplifier configured to amplify a multi-band signal split across a plurality of inputs of the multi-band multi-order power amplifier as a plurality of multi-band split signals, the plurality of inputs comprising a different input for each of N orders of the multi-band multi-order power amplifier where N is greater than or equal to 2; and a digital upconversion system for the multi-band multi-order power amplifier that is configured to control a gain, phase, and delay for each of M frequency bands of the multi-band signal for each of at least N−1 of the plurality of multi-band split signals independently from the gains, phases, and delays of other multi-band split signals such that one or more performance parameters of the multi-band multi-order power amplifier are optimized.
