Abstract
A feedforward amplifier is disclosed in which either the main amplifier or the auxiliary amplifier includes at least three parallel signal paths. Each of the signal paths includes a complex gain adjuster. In addition, a feedforward amplifier is disclosed in which a plurality of control linearizers compensate for nonlinearities in the response of signal adjusters to control inputs.
