Abstract

UN FILTRO DE CERAMICA (144, 118) INCLUYE UNA FUNCION DE FILTRO PARABANDA MULTIPLE CERO. EL FILTRO CERAMICO TIENE UN BLOQUE DIELECTRICO (210) CON SUPERFICIES SUPERIOR E INFERIOR Y AL MENOS DOS AGUJEROS (221-227), QUE SE EXTIENDEN DESDE LA SUPERFICIE SUPERIOR HACIA LA INFERIOR DEL BLOQUE. EL BLOQUE (210) ESTA SELECTIVAMENTE ABIERTO CON UN MATERIAL CONDUCTOR, PARA PROVEER UNA RESONADORA LINEA DE TRANSMISION POR CADA UNO DE LOS DOS AGUJEROS. EL FILTRO TAMBIEN INCLUYE UN ELECTRODO DE ENTRADA (214) ACOPLADO A LOS MEDIOS DIELECTRICOS A UNA DISTANCIA PREDETERMINADA DE UN PRIMER AGUJERO (201) Y UN ELECTRODO DE SALIDA (216) ACOPLADO A LOS MEDIOS DIELECTRICOS A UNA DISTANCIA PREDETERMINADA DE OTRO AGUJERO (207). FINALMENTE, EL CHAPADO CONDUCTOR (240), EN LA FORMA DE UNA LINEA DE TRANSMISION, ESTA CONTIGUAMENTE DISPUESTA EN LOS MEDIOS DIELECTRICOS ADYACENTES A LOS DOS AGUJEROS Y ACOPLADOS A ELLO PARA PROVEER UNA FUNCION DE FILTRO PARABANDA CON UN ARO REPRESENTADO EN CADA AGUJERO.
