Abstract
An antenna tuner receives outputs of detectors coupled to an input and/or an output of each power amplifier (PA) of a plurality of PAs of a multiple antenna system. A processor of the antenna tuner is configured to process the detector outputs and to generate at least one of a gm gate bias value and a cascode gate bias value to be applied to gm and cascode gates, respectively, of a last stage of each of the PAs to change the shape of an input amplitude-to-output amplitude (AM-AM) response of each of the PAs independently of one another. The processor can also be configured to process the detector outputs to generate a varactor bias value to be applied to a terminal of a varactor of each of the PAs to change the shape of an input amplitude-to-output phase shift (AM-PM) response of each of the PAs independently of one another.
