CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishLow-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.
