Abstract
EN UN SISTEMA DE CONEXIONES PARA UN SINTONIZADOR DE HF DONDE SE PRETENDE ACOPLAR UN CIRCUITO DE IF A LA SALIDA DE UN MEZCLADOR, QUE POSEE UN TRANSISTOR FUNCIONANDO EN CONEXION BASICA, ESTA PREVISTA LA CONEXION DE UN ESCALON AMPLIFICADOR ENTRE LA SALIDA DEL MEZCLADOR Y EL CIRCUITO DE IF. EL CIRCUITO AMPLIFICADOR PRESENTA UN TRANSISTOR QUE FUNCIONA EN CONEXION DE EMISOR Y CUYA BASE ESTA ACOPLADA AL COLECTOR DEL TRANSISTOR MEZCLADOR Y SU COLECTOR CON EL CIRCUITO DE IF.
