Abstract

SE PROVEE UN AMPLIFICADOR DE POTENCIA PARA AMPLIFICAR UNA SEÑAL DE RADIO FRECUENCIA TAL COMO EN UNA EMISION EN FORMA MODULADA PARA USO EN RADIO CELULAR GSM. EL AMPLIFICADOR TIENE MEDIOS, TALES COMO UNA MEMORIA ROM (16), PARA PRODUCIR UNA PREDETERMINADA SECUENCIA DE VALORES EN RESPUESTA A UN IMPULSO DE CONTROL. SE PROVEEN MEDIOS (21) PARA CONVERTIR CADA VALOR EN UNA SEÑAL DE CONTROL DE POTENCIA, Y SE PROVEEN MEDIOS (9) DE CONTROL PARA CONTROLAR LA POTENCIA DE SALIDA DEL AMPLIFICADOR DE ACUERDO CON DICHA SEÑAL DE CONTROL DE POTENCIA. DE ESTA MANERA LA CARACTERISTICA POTENCIA/TIEMPO SE PUEDE TOMAR O HACER EN LA FORMA QUE EMULE UN COSENO. LA INVENCION TAMBIEN PROVEE MEDIOS DE SELECCION DE POTENCIA PARA SELECCIONAR UN NIVEL NOMINAL DE SALIDA DENTRO DE UNA PLURALIDAD DE VALORES DISCRETOS Y PARA SELECCIONAR SUB-NIVELES DE POTENCIA NO ESTABLECIDOS EN DICHOS SELECCIONADOS NIVELES. SE GRABA UNA INDICACION CON EL NIVEL DE POTENCIA NOMINAL AL QUE REPRESENTA EL SUBNIVEL ELEGIDO.FIG 1.
