Abstract

SE DESCRIBE UN FILTRO DE PASO DE FRECUENCIAS ENTRE BANDAS, DE CARACTERISTICA EN PEINE, CON SECCION CIRCULAR TRANSVERSAL HECHA DE VARILLAS INTERNAS (A1 A A5), QUE CONSTITUYEN LOS RESONADORES DEL FILTRO Y SE LLEVAN A RESONANCIA MEDIANTE LA UTILIZACION DE TORNILLOS DE SINTONIZACION (S1 A S5), Y ALTERNANDO CON TORNILLOS DE ACOPLAMIENTO (V1 A V4). EN EL FILTRO, LAS VARILLAS (A1 A A5) SE INTRODUCEN EN TAL FORMA QUE CADA UNA GIRA EN RELACION RESPECTO A LA PRECEDENTE, EN UN ANGULO DE 0 < 90 , EN TANTO QUE LOS TORNILLOS DE ACOPLAMIENTO (V1 A V4) ESTAN COLOCADOS FORMANDO UN ANGULO INTERMEDIO. PARA CARACTERISTICAS ELECTRICAS IGUALES, LA LONGITUD DEL FILRO ES TAMBIEN UNA FUNCION DEL ANGULO DE ROTACION DE LAS VARILLAS (A1 A A5).
