Abstract
FILTRO DE ONDAS ACUSTICAS SUPERFICIALES RESONANTE DE BAJAS PERDIDAS UTILIZANDO ACOPLADOR-REFLECTOR MULTISTRIP. APLICABLE AL FILTRADO DE SEÑALES ELECTRICAS DE ALTA FRECUENCIA Y QUE ESTA CONSTITUIDO MEDIANTE UNAS METALIZACIONES SOBRE UN SUSTRATO PIEZOELECTRICO (5) QUE DETERMINAN DOS ACOPLADORES-REFLECTORES MULTISTRIP (1 Y 2) QUE LIMITAN Y ACOPLAN DOS CAVIDADES RESONANTES, ENCONTRANDOSE ENTRE LOS ACOPLADORES-REFLECTORES (1 Y 2), DOS TRANSDUCTORES INTERDIGITADOS (3 Y 4) CONECTADOS EN PARALELO MEDIANTE DICHOS ACOPLADORES-REFLECTORES (1 Y 2), Y FORMADOS POR ELECTRODOS (10, 12 Y 13) DIMENSIONADOS MEDIANTE LA TECNICA DE APODIZACION, CONSIGUIENDOSE ASI BAJAS PERDIDAS Y UN ELEVADO RECHAZO DE BANDA EN LA RESPUESTA DEL FILTRO. ESTE FILTRO EMPLEA UN SUSTRATO PIEZOELECTRICO (5) CON ALTO COEFICIENTE DE ACOPLAMIENTO, PREFERENTEMENTE LINBO3 CON ORIENTACION DE 128 EL EJE Y Y CORTE SEGUN EL EJE X, QUE PERMITE LA REDUCCION DE SU TAMAÑO EN SU APLICACION A FRECUENCIAS VHF.
