Abstract

Se describe un amplificador de potencia compuesto (100) para la amplificación de una señal de entrada en una señal de salida. El amplificador de potencia compuesto (100) comprende un puerto de entrada (170) para recibir la señal de entrada, y un puerto de salida (180) para proporcionar la señal de salida. Además, el amplificador de potencia compuesto (100) comprende un primer conjunto (110) de sub-amplificadores, que comprende al menos dos sub-amplificadores (111, 112), en donde las al menos dos sub-amplificadores (111, 112) están dispuestos a lo largo de un ahusamiento de una primera línea de transmisión (151), en donde la primera línea de transmisión (151) está conectada al primer conjunto (110) de sub-amplificadores y el puerto de salida (180). Además, el amplificador de potencia compuesto (100) comprende un segundo conjunto (120) de sub-amplificadores, que comprende al menos dos sub-amplificadores (121, 122), en donde los al menos dos sub-amplificadores (121, 122) están dispuestos a lo largo de un ahusamiento de una segunda línea de transmisión (152), en donde la segunda línea de transmisión (152) se conecta con el segundo conjunto (120) de los sub-amplificadores y el puerto de salida (180).
