CINECA IRIS Institutional 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.
EnglishThe present paper was focused on the extraction of a GaAs pHEMT nonlinear model meant for mixer design. The model is based on an equivalent circuit that is analytically extracted from DC and multi-bias S-parameter measurements. The look-up table approach is used to implement the model in a nonlinear RF circuit simulator. The model accuracy is extensively verified by comparing device measurements and simulations under a wide range of operating conditions. Furthermore, to corroborate the validity of the model, the design of a Q-band up-converter is considered.
