X-Parameter Phase and Load of Nonlinear Devices

At present, nonlinear devices are just beginning to develop, and the X-parameter method is the most reliable of all methods. The difference between the X parameter and the S parameter is that the X parameter introduces an absolute phase, which plays a very important role in constructing the X parameter model. The different load affects the extraction of X parameters by the form of reflected waves, which is also an important part of X-parameter modeling. Studying the impact of both on X-parameter modeling is an important task in X-parameter modeling.
