Abstract

EN LA AMPLIFICACION DE ALTA FRECUENCIA SE MUESTRAN SINTONIZADORES EN PREAMPLIFICACION GENERAL (1, 1'', 1'''') CON TETRODOS MOS (4) PARA CADA ZONA PARCIAL DE LOS SINTONIZADORES. DE ACUERDO CON ESTA INVENCION SE ALCANZA LA CONMUTACION DE FORMA QUE LA CONEXION DE FUENTE (S) DE LA PREAMPLIFICACION ACTIVADORA (1), ES CONMUTABLE SOBRE UNA RESISTENCIA (10) A TRAVES DE UN DISPOSITIVO DE CONMUTACION (11) SOBRE POTENCIAL DE REFERENCIA.
