Abstract
A feed-forward linearization of a traveling wave tube amplifier linearizes the transfer function of the tube through a linearization voltage derived at baseband from the instantaneous amplitude of the input signal to control the cathode voltage causing induced phase modulation to offset the normal amplitude modulation to phase modulation conversion distortion. The feed forward linearization control results in reduced distortion for improved phase linearization of the tube over the operating range of the tube.
