Abstract—The power mixer array is presented as a novel power
generation approach for non-constant envelope signals. It com-
prises several power mixer units that are dynamically turned on
and off to improve the linearity and back-off efficiency. At the
circuit level, the power mixer unit can operate as a switching
amplifier to achieve high peak power efficiency. Additional circuit
level linearization and back-off efficiency impro
