Abstract :
A Design of Experiments (DOE) analysis of a feed-forward amplifier system is presented. The frequency behavior of feed-forward components is for the first time considered in the analysis. It is shown that, for the simulation and specification of a feed-forward system, it is possible to include the amplitude and frequency dispersion of the components in the tolerance specification of the control elements. Subsequently, it is indicated with a case study that the tolerances required for the second loop to reach a certain level of intermodulation are much more stringent than those for the first loop
