An electrothermal BSIM3 model for large-signal operation of RF power LDMOS devices

Abstract: Aislma -An electrothermal BSIM3 model for large signal operation of RF power LDMOS devices has been developed. The physically-based model was carefully calibrated to pulsed currentlvoltage characteristics and biasdependent capacitance measurements. Internal matching networks and influence from the package were included in a physical way. The implemented electrothermal coupling exhibited good numerical stability during largesignal operation and the model correlates well to measurements of RF functional characte… Show more

“…Terminating the transistor with the optimum fundamental and harmonic load impedances (as specified in Table I) to achieve maximum efficiency, an output power of 41.5 dBm and a PAE of 78% with a transducer gain of 16 dB was achieved. These measurements were compared to harmonic balance simulation results based on a compact model of the packaged device [49]. Good agreement between measurement results and time domain simulation was achieved.…”

“…Con esa información, el ingeniero diseñador de RF puede, por ejemplo, evitar polarizar el transistor en esas condiciones antes de la implementación del amplificador de potencia final, ahorrando tiempo y dinero en la industria de los transistores de microondas. Una de estas técnicas es el modelo térmico mostrado en [4], el cual utiliza una red con una resistencia térmica y un capacitor térmico en el drenador del transistor intrínseco. Este método permite modelar a dispositivos LDMOS de hasta 10 A de corriente de drenador.…”
