Abstract
An antenna array includes a plurality of power amplifiers, each having a signal input, a signal output coupled to a cell of the antenna array, and a power input. The antenna array includes a plurality of power supplies, each power supply individually and separately coupled to a corresponding one of the plurality of power amplifiers at a respective power input. The antenna array further includes single a pre-distortion linearizer with a linearizer input that receives a signal and a linearizer output that is coupled to each signal input of each of the plurality of power amplifiers. Each power amplifier is operated in gain compression by setting its operating voltage according to a power output of the power amplifier.
