Nonlinear device model of microwave power GaN HEMTs for high power-amplifier design (2004, methodology): “, biasing the device below [3]—in addition to a very good small-signal IMD description, our model can also predict, with very good accuracy, the observed largesignal IMD sweet spot.”
Overview of radar waveform diversity (2016, background): “Nonlinear distortion is primarily caused by the typical HPA operation in saturation (particularly for tube-based HPAs), thereby creating the formation of intermodulation products (harmonics) from the pairwise multiplication of different frequency components in the waveform [102].”
A comparative overview of microwave and wireless power-amplifier behavioral modeling approaches (2005, background): “AM and AM–PM conversion [1], [5] constitute the PA's memoryless Fig.”
Fundamentals of Wireless Information and Power Transfer: From RF Energy Harvester Models to Signal and System Designs (2018, methodology): “The diode nonlinear model is a simple form of a memoryless polynomial model that has been widely adopted and validated in the RF literature [4], [43], [56].”
