Abstract
LA INVENCION SE REFIERE A AMPLIFICADORES DE POTENCIA, COMO POR EJEMPLO AMPLIFICADORES DE POTENCIA PULSADA, PARA AMPLIFICAR LAS SEÑALES DE RADIOFRECUENCIA Y A UN METODO PARA AMPLIFICAR LAS SEÑALES DE RADIOFRECUENCIA. SEGUN LA INVENCION, EL AMPLIFICADOR DE POTENCIA RESPONDE A UNA SEÑAL DE CONTROL DEL NIVEL DE POTENCIA PARA ASI AMPLIFICAR LAS SEÑALES DE RADIOFRECUENCIA PARA DEFINIR UNA DE ENTRE LAS VARIAS ENVOLVENTES DE POTENCIA DE SALIDA DEL AMPLIFICADOR. EL AMPLIFICADOR DE POTENCIA CONSTA DE MEDIOS (110, 112, 114) PARA GENERAR UNA SEÑAL DE VARIACION TEMPORAL PREDETERMINADA QUE REPRESENTA UNA PREDETERMINADA DE LAS MUCHAS ENVOLVENTES DE POTENCIA DE SALIDA DEL AMPLIFICADOR, MEDIOS (130) PARA MODIFICAR LA SEÑAL DE VARIACION TEMPORAL EN RESPUESTA A LA SEÑAL DE CONTROL DEL NIVEL DE POTENCIA (124) PARA LA DEFINICION DE UNA ENVOLVENTE DE POTENCIA DE SALIDA SELECCIONADA Y MEDIOS DE CONTROL (108) PARA CONTROLAR LA POTENCIA DE SALIDA DEL AMPLIFICADOR EN RESPUESTA A LA SEÑAL DE VARIACION TEMPORAL PARA AMPLIAR LA SEÑAL DE RADIOFRECUENCIA SEGUN LA SELECCIONADA DE LAS VARIAS ENVOLVENTES DE POTENCIA DE SALIDA. LA SEÑAL DE VARIACION TEMPORAL PUEDE SER UNA SECUENCIA DE LOS VALORES ALMACENADOS EN LA MEMORIA (114). EL MEDIO MODIFICADOR PUEDEN SER UN LIMITADOR QUE LIMITA LA SEÑAL DE VARIACION TEMPORAL A UN VALOR QUE DEPENDE DE LA SEÑAL DE CONTROL DEL NIVEL DE POTENCIA O UN MULTIPLICADOR (130) QUE MULTIPLICA LA SEÑAL DE VARIACION TEMPORAL POR UN VALOR QUE DEPENDE DE LA SEÑAL DE CONTROL DEL NIVEL DE POTENCIA O UN SUBSTRACTOR QUE SUBSTRAE UN VALOR DE LA SEÑAL DE VARIACION TEMPORAL QUE DEPENDE DE LA SEÑAL DE CONTROL DEL NIVEL DE POTENCIA.
