Abstract
DISPOSICION DE FILTRO PARA SUPRESION DE BANDA QUE UTILIZA FILTROS PASA-BANDA, CADA UNO DE ELLOS TERMINADO EN UNA CARGA ADAPTADA. UN CIRCUITO HIBRIDO EN CUADRATURA DIVIDE LAS SEÑALES DE ENTRADA Y LAS APLICA A LOS FILTROS PASA-BANDA. LAS SEÑALES INCLUIDAS EN LA BANDA DE SUPRESION SON DISIPADAS POR LOS FILTROS Y CARGAS ADAPTADAS, MIENTRAS QUE LAS SEÑALES DESEADAS SON REFLEJADAS. LAS SEÑALES REFLEJADAS SON DESPUES COMBINADAS POR EL CIRCUITO HIBRIDO EN CUADRATURA PARA PROPORCIONAR LA SALIDA DE LA BANDA SUPRIMIDA. ESTA DISPOSICION SE PROYECTA CONMUTABLE ENTRE UN MODO DE PASA TODO Y EL MODO DE SUPRESION DE BANDA HABILITANDO UNOS DIODOS PIN ENTRE EL CIRCUITO HIBRIDO EN CUADRATURA Y LOS FILTROS PASA-BANDA.
