1. A computer-implemented method for designing an RF device, comprising:
modelling a current design of the RF device as a model device in a simulator;
applying a simulated input power sweep on the model device;
measuring, by a processor, an output sweep of amplitudes for the model device in response to the simulated input power sweep;
calculating, by a processor, a parameter of a statistical distribution based on a modulation scheme for the RF device;
computing, by a processor, error vector magnitude values versus output power based on the input sweep, output sweep, and the statistical distribution, wherein the statistical distribution provides a matrix of weighting factors for the computing of the error vector magnitude values;
determining, by a processor, if the RF device is within a specified tolerance based on the error vector magnitude values; and
adjusting the current design of the RF device based on the determining.
