Abstract

UN AMPLIFICADOR DE POTENCIA PARA UNA CARGA DE PLACA DE UN TRANSMISOR AM, RF INCLUYE VARIAS ETAPAS DE CONMUTACION CADA UNA DE LAS CUALES SE ALIMENTA DE UNA FUENTE DE CC. CADA ETAPA ES CONMUTADA DESDE LA NO-ALIMENTACION HASTA LA SATURACION COMO RESPUESTA A LA AMPLITUD DE UNA FUENTE QUE SOBREPASA UNA AMPLITUD DE UMBRAL DURANTE LA ETAPA; CADA ETAPA TIENE UN UMBRAL DIFERENTE. LOS UMBRALES Y LA FUENTE ESTAN COLOCADOS DE TAL FORMA QUE LAS RESPUESTAS DERIVADAS ENTRE LOS TERMINALES DE SALIDA DE LAS ETAPAS CAMBIAN ENTRE CERO Y AMPLITUDES PREDETERMINADAS SEGUN CAMBIA LA AMPLITUD DE LA FUENTE EN RELACION CON LOS UMBRALES DE LAS DIFERENTES ETAPAS. LAS RESPUESTAS DE LAS DIFERENTES ETAPAS SE SUMAN. UNA ONDA TRIANGULAR CON UNA PEQUEÑA AMPLITUD MAXIMA CONSTANTE EN RELACION AL VALOR MAXIMO DE LA FUENTE CAMBIA EFECTIVAMENTE EL UMBRAL DE CADA ETAPA. DE VEZ EN CUANDO LOS UMBRALES DE ETAPAS DIFERENTES SE CAMBIAN DE TAL FORMA QUE EN MOMENTOS DISTINTOS ETAPAS DIFERENTES ESTAN SIN ALIMENTACION Y SON CONDUCIDAS PARALA MISMA AMPLITUD DE LA FUENTE DE MODULACION, MIENTRAS SE FACILITA LA MISMA RESPUESTA SUMADA PARA LA MISMA AMPLITUD DE LA FUENTE DE MODULACION.
