Abstract
Systems and methods are taught whereby amplification of narrowband signals may be accomplished by linear power amplifiers requiring the presence of a communicated broadband signal in order to make internal adjustments necessary for linear operation. A preferred embodiment is described utilizing an input of a distributed amplifier assembly unused by the signals of interest in order to inject an emulated CDMA tone operable as a pilot tone for use by the linear power amplifiers.
