Using Pulsed I/V measurement results over a 15 W GaN HEMT, the deviation in the Vdd-to-AM modulation profile is estimated. System-level calculations, in the presence of gateto- drain capacitance contribution to carrier feedthrough, allow the evaluation of the secondary role of this dispersion effect.}, publisher = {URSI 2009, XXIV Simposium Nacional de la Unión Científica Internacional de Radio, Santander}, title = {Distorsión no lineal en un transmisor polar debida a la característica Ron(VDD) del dispositivo GaN HEMT}, author = {Marante Torres, Reinel and García García, José Ángel and Cabral, Pedro Miguel da Silva and Pedro, Jose Carlos Esteves Duarte}, }
