How to extract Unilateral High Frequency memory (U-HF) model for Mixer (MIX). The MIX-U-HF model is the simplest nonlinear
mixer model. Extracting this model requires little information about the component, i.e. 1-tone CW measurements, performed
on a nominal load impedance. It therefore takes into account only the dispersive effects present in the operating
band of the mixer and ignores other memory effects such as those due to polarization or heating. It is a fixed LO
signal model. Only the LO frequency variations are taken into account. This model does not take into
account load impedance changes.
