Abstract

PARA LA AMPLIFICACION DE ALTA FRECUENCIA SE MUESTRAN SINTONIZADORES EN PREAMPLIFICACION GENERAL (1, 1'') CON TETRODOS MOS (4, 4'') PARA CADA CAMPO PARCIAL DEL SINTONIZADOR. DE ACUERDO CON ESTA INVENCION SE CONSIGUE LA CONMUTACION ENTRE DOS CAMPOS, DE FORMA QUE AMBOS PREAMPLIFICADORES (1, 1'') ESTAN CONECTADOS EN UNOS BORNES DE SALIDA (12) DE EQUIPO DE CONEXION (9) UNIDO AL BORNE DE POTENCIA DE REFERENCIA (6) Y AMBOS PREAMPLIFICADORES (1, 1'') ESTAN ACOPLADOS UNO CON OTRO, DONDE -DEPENDIENDO DEL ESTADO DE CONMUTACION DE LOS BORNES DE SALIDA (12)DE LOS PREAMPLIFICADORES (1, 1'') ES ACTIVABLE.
