Measuring nonlinear differential RF amplifiers using one single-ended source

A measurement procedure for the nonlinear baseband response of a differential amplifier is proposed using the network analyzer for nonlinear systems (LSNA). The setup uses only 1 single-ended RF generator. A simplified nonparametric model for the frequency response of the device and its nonlinear contributions over a wide power range is proposed, measured and validated experimentally.
