Abstract

El microfiltro activo compuesto esencialmente por una parte activa que comprende un circuito inversor de signo compuesto por un amplificador operacional (13), dos resistencias y la impedancia objeto de adaptación (12) y una parte pasiva que comprende condensadores, bobinas y resistencias. El microfiltro activo se dispone en un dispositivo autoinstalable que comprende un circuito de alimentación de la parte activa; y donde el objetivo es eliminar las reflexiones causadas por tramos de línea sin adaptar que interfieren en el correcto funcionamiento de la red en acceso a banda ancha sobre el estándar VDSL2.
