Simultaneous linearization of multiple power amplifiers with independent power

A method for simultaneous linearization of a plurality of power amplifiers, each of the plurality of power amplifiers having independently set operating voltages for one of a plurality of antenna cells of an antenna array, the method comprising:

• selecting an operating voltage for an individual power amplifier of the plurality of power amplifiers, the operating voltage for the individual power amplifier selected to maintain the individual power amplifier at a predetermined gain compression level;
• independently of each other power amplifier, setting the operating voltage for the individual power amplifier of the plurality of power amplifiers at the selected operating voltage;
• and
• routing a signal from a single pre-distortion linearizer to the individual power amplifier, the individual power amplifier having a signal output individually and separately coupled to a corresponding antenna cell of the plurality of antenna cells.

An antenna array comprising:

• a first power amplifier of a plurality of power amplifiers, each of the plurality of power amplifiers having a signal input, a signal output, and a power input;
• a first power supply of a plurality of power supplies, each of the plurality of power supplies having a power output coupled to a respective power input of one of the plurality of power amplifiers, wherein the power output of the first power supply is set to operate the first power amplifier at a predetermined gain compression;
• a single pre-distortion linearizer with a linearizer input and a linearizer output, the linearizer output coupled to each respective signal input of each of the plurality of power amplifiers;
• and
• a plurality of antenna cells, each of the plurality of antenna cells individually and separately coupled to a respective one signal output of each of the plurality of power amplifiers.
