ABSTRACT:
The present invention is a method and a feed forward circuit incorporating an automatic gain and phase controller for controlling amplitude gain and phase shift being applied to an input signal of an amplifier undergoing changing conditions. The automatic gain and phase controller is configured to monitor the amplifier output signals and manipulate the amplitude and phase of the amplifier input signal (via a gain and phase adjuster) such that the amplitude and phase of the amplifier output signals are substantially identical to those of previous amplifier output signals.
