Abstract
FILTRO DE CAVIDADES BIMODO. FORMADO POR UNA O MAS CAVIDADES RESONANTES EN LAS QUE SE PRODUCEN DOS MODOS DE RESONANCIA A DOS FRECUENCIAS DIFERENTES F1 Y F2, TENIENDO AMBOS MODOS ESENCIALMENTE LAS MISMAS DISTRIBUCIONES DE CAMPO PERO ROTADO 90 GRADOS UNO RESPECTO DEL OTRO. CADA CAVIDAD COMPRENDE UN ELEMENTO DE SINTONIA (TSA) PARA. SINTONIZAR LA FRECUENCIA RESONANTE F1 DEL PRIMER MODO SEGUN UN PRIMER EJE, UN ELEMENTO DE SINTONIA (TSB) PARA SINTONIZAR LA FRECUENCIA RESONANTE F2 DEL SEGUNDO MODO SEGUN UN SEGUNDO EJE PERPENDICULAR AL PRIMERO, UNOS MEDIOS DE ACOPLO DE ENTRADA (IC) Y UNOS MEDIOS DE ACOPLO DE SALIDA (OC) PARA, RESPECTIVAMENTE APLICAR Y EXTRAER UNA SEÑAL DE RADIOFRECUENCIA DE LA CAVIDAD SEGUN EJES NO PARALELOS A LOS DE RESONANCIA. LA SINTONIA DEL FILTRO SE REALIZA UNICAMENTE MEDIANTE EL USO DE DOS ELEMENTOS DE SINTONIA, LO QUE IMPLICA UN MENOR COSTE DEL FILTRO Y EL EMPLEO DE MENOS TIEMPO PARA SINTONIZAR EL MISMO.
