ABSTRACT:
A robust amplifier consists of two delay lines linked by a number of discrete amplifiers. Distortion correction is carried out by distortion feed forward. This is achieved by sampling the output of each amplifier at a coupler and then subtracting this sample from the input signal to later amplifiers along the delay line at directional coupler. As a result each discrete amplifier's distortion is corrected by all of the following discrete amplifiers in the amplifying circuit.
