Abstract
A circuit is provided, having a feed forward linear power amplifier configured with two or more error correction loops (). Each of the error correction loops includes a band pass filter (). Each of the band pass filters () is tuned to a different frequency range. A controllable frequency oscillator () can be coupled to an input of the error correction loops. A controller sweeps the frequency of the controllable frequency oscillator over the frequency range corresponding to each of the band pass filters ().
