Abstract

EN LOS DERIVADORES DE ACOPLADORES DIRECCIONALES CONOCIDOS PARA EL DESACOPLAMIENTO EN BANDA ANCHA DE UNA PARTE DE LA ENERGIA DE SEÑAL DE ALTA FRECUENCIA TRANSMITIDA POR UNA LINEA FISICA, QUE SE COMPONEN DE AL MENOS DOS DERIVADORES INDIVIDUALES CONECTADOS EN CASCADA, DE LOS QUE AL MENOS UNO ESTA CONSTRUIDO CON LA TECNICA DE LOS ACOPLADORES DIRECCIONALES CON UN TRANSFORMADOR DE CORRIENTE Y CON UN TRANSFORMADOR DE TENSION ASI COMO CON UNA RESISTENCIA DE TERMINACION (R) INTERNA CONECTADA UNILATERALMENTE A MASA, NO ES POSIBLE OBTENER O SOLO EN POCOS CASOS Y CON UN COSTE ELEVADO, ATENUACIONES DE DERIVACION (MENOR O IGUAL) 13 DB CON UN DESACOPLAMIENTO SUFICIENTE DE LA SALIDA (A) DE LA CONEXION DE DERIVACION (AB) Y CON VALORES DE ATENUACION DE PASO Y DE ATENUACION DE RETORNO FAVORABLES. PARA EVITAR ESTOS INCONVENIENTES DE LA FORMA MAS SENCILLA Y ECONOMICA SE PREVE, SEGUN EL INVENTO, QUE LA RESISTENCIA DE TERMINACION INTERNA DE CADA DERIVADOR DE ACOPLADOR DIRECCIONAL INDIVIDUAL ESTE FORMADA, POR MEDIO DE LA UNION DE SU CONEXION DE DERIVACION (2, 35) CON LA DEL DERIVADOR INDIVIDUAL QUE SE HALLA INMEDIATAMENTE DELANTE, POR LA IMPEDANCIA DE DERIVACION DE ESTE, QUE LA DERIVACION DEL ULTIMO DERIVADOR DE ACOPLADOR DIRECCIONBAL INDIVIDUAL SEA LA CONEXION DE DERIVACION (AB) UNICA Y QUE LAS CORRIENTES DESACOPLADAS DE LOS TRANSFORMADORES DE CORRIENTE (U1, U2, U4) POSEAN AL MENOS APROXIMADAMENTE LA MISMA FASE.
