Abstract: Este proyecto presenta la metodología de diseño de un amplificador de potencia Doherty (DPA) para aplicaciones en tecnología WiMAX, con frecuencia de trabajo de 3.5 GHz; al cual se adiciona una etapa de pre-amplificación con el objetivo de incrementar los niveles de ganancia dentro de la región Doherty, donde se tiene la mayor eficiencia del amplificador. Para ello se utiliza la estrategia de extracción de parasitas para caracterizar los dispositivos GaN HEMT de Cree Inc., y la validación de los resultados por medio del software de Keysight Advanced Design System (ADS) ®. Donde se obtiene como resultado de las simulaciones una máxima eficiencia de potencia agregada (PAE) de 44%, potencia de salida en saturación de hasta 43dBm y valores de ganancia en la zona Doherty que superan los 20dB, que comparado con el amplificador Doherty en su estructura básica representa un incremento mayor al 110%.
