Abstract

EN UN FILTRO COMBINADOR PARA UN SISTEMA TELEFONICO CELULAR, HAY UN RESONADOR COAXIAL QUE INCLUYE UNA CAVIDAD RECTANGULAR. DENTRO DE LA CAVIDAD RECTANGULAR HAY UN CONDUCTOR CENTRAL QUE TIENE UNA PLACA EN FORMA OVALADA. EL CONDUCTO CENTRAL Y LA PLACA DE FORMA OVALADA SE DESPLAZAN DENTRO DE LA CAVIDAD RECTANGULAR PARA ESTABLECER LA FRECUENCIA DEL RESONADOR FUNDAMENTAL. ADYACENTE A LA PLACA CONDUCTORA CENTRAL ESTA UN ELEMENTO EN FORMA DE VIGA DOBLE EN T, QUE GIRA PREFERENTEMENTE MEDIANTE UN EJE ACOPLADO A UN MOTOR DE VELOCIDAD GRADUAL. LA ROTACION DEL ELEMENTO EN FORMA DE VIGA DOBLE EN T, PROPORCIONA AJUSTE DE FRECUENCIAS O SINTONIA PARA EL RESONADOR COAXIAL.
