Low-frequency thermal transients may give a relevant contribution to the generation of intermodulation distortion in nonlinear RF subsystems such as power amplifiers, where significant self-heating takes place. The pa-per discusses a simple and accurate behavioural model whereby such effects may be simulated with excellent ac-curacy and high computational speed. The model relies upon a parametric description of the relationships between the linear and nonlinear subsystem responses, and makes use of a relaxation method to efficiently evaluate the temperature waveforms.

Abstract: | Low-frequency thermal transients may give a relevant contribution to the generation of intermodulation distortion in nonlinear RF subsystems such as power amplifiers, where significant self-heating takes place. The pa-per discusses a simple and accurate behavioural model whereby such effects may be simulated with excellent ac-curacy and high computational speed. The model relies upon a parametric description of the relationships between the linear and nonlinear subsystem responses, and makes use of a relaxation method to efficiently evaluate the temperature waveforms. |
