Abstract
Un aparato para compensar la distorsión de fase en una señalmodulada amplificada en potencia (eout ) a la salida de un amplificador de potencia (40), donde el amplificador tiene una entrada conectada a una salida de un bucle de enganche de fase y de conversión ascendente (30-39), donde el bucle incluye un respectivo primer bucle de retroalimentación y un respectivo segundo bucle de retroalimentación (33 y 36), donde el primer bucle de retroalimentación (33) está conectado a un medio de derivación (37) para derivar parte de una señal modulada (epha ) a la entrada del amplificador de potencia (40) y el segundo bucle de retroalimentación (36) se conecta a un medio de derivación (38) que deriva parte de la señal modulada amplificada en potencia (eout ) en la salida del amplificador de potencia (40); el aparato se caracteriza por que cada uno de los bucles de retroalimentación (33, 36) está conectado a una entrada respectiva de un medio de combinación (35) que combina las dos señales de entrada desde los respectivos bucles de retroalimentación (33, 36) para proveer una señal de retroalimentación (efdb ) en el bucle de enganche de fase y bucle de conversión ascendente (30-39).Un método para compensar la distorsión de fase en una señal modulada amplificada en potencia a la salida de un amplificador de potencia (40), donde el amplificador (40) tiene una entrada conectada a una salida del bucle de enganche de fase y de conversión ascendente (30-39) y donde el bucle incluye un primer y un segundo bucle de retroalimentación (33,36); dicho metodo comprende:- derivar parte de la señal modulada a la entrada del amplificador de potencia (40) a través del primer bucle de retroalimentación (33); y - derivar parte de la señal modulada amplificada en la salida del amplificador de potencia (40) a través del segundo bucle de retroalimentación (36);...
