Abstract

UNA UNIDAD AMPLIFICADORA DE POTENCIA IMPLEMENTADA CON UN MODULO AMPLIFICADOR DE POTENCIA Y CONECTADA A UN TRANSMISOR/RECEPTOR DE UN APARATO TELEFONICO RADIO MOVIL. SE CONECTA UN AMPLIFICADOR DE CORRIENTE CC A UNA TERMINAL DE CONTROL DE TENSION INCLUIDA EN EL MODULO PA. DIFERENTES TENSIONES GENERADAS POR CIRCUITOS DE FUENTES DE POTENCIA INDIVIDUALES SE APLICARAN SELECTIVAMENTE AL AMPLIFICADOR DE CORRIENTE CC. LA UNIDAD SE OPERA CON CUALQUIERA DE LOS MODULOS PA CADA UNO DE LOS CUALES APLICARA UNA TENSION ESPECIAL A UNA TERMINAL DE CONTROL DE TENSION DE LOS MISMOS.
