Abstract

SE PRESENTA UN METODO PARA CONTROLAR UN AMPLIFICADOR EXTERNO DE FRECUENCIAS DE RADIO DE UN RADIOTELEFONO Y UN SISTEMA DE CONTROL PARA EL MISMO. EL AMPLIFICADOR DE POTENCIA DEL LADO DE TRANSMISION DEL AMPLIFICADOR DE RADIOFRECUENCIA SE CONTROLA PARA ENCENDERSE Y APAGARSE, SOBRE LA BASE DE AL MENOS UNA SEÑAL DE CONTROL (BENA1, BENA2) QUE SE INTRODUCE EN EL AMPLIFICADOR DE RADIOFRECUENCIA DE FORMA SEPARADA DE UNA SEÑAL QUE HA DE TRANSMITIRSE DESDE EL RADIOTELEFONO. LA SEÑAL DE CONTROL (BENA1, BENA2) CONTIENE INFORMACION ACERCA DEL INSTANTE DEL INICIO Y DE FINALIZACION DE LA TRANSMISION.
