Abstract

UN OSCILADOR CONTROLADO POR TENSION (VCO) QUE PRESENTA CARACTERISTICAS DE LINEALIDAD EN FRECUENCIA MEJORADAS. SE DISPONE EN UNA GUIA DE ONDA DE BANDA ANCHA, CON RESALTES, UNA LINEA RADIAL, JUNTO CON UN DIODO VARACTOR, GEOMETRIA DE DISCO, PARA PRODUCIR UN OSCILADOR CONTROLADO POR TENSION LINEALIZADO EN FRECUENCIA. UN DISPOSITIVO DE RESISTENCIA NEGATIVA ES EMBUTIDO DENTRO DE LA GUIA DE ONDA Y ACOPLADO COAXIALMENTE POR MEDIO DE UN TRANSFORMADOR DE IMPEDANCIAS A LA CAVIDAD DE LA GUIA DE ONDA. ESTA INVENCION UTILIZA UN DISCO RESONANTE, PARA TRANSFORMAR LA IMPEDANCIA DE MICROONDAS DE UN ELEMENTO GENERADOR DE UNA SEÑAL QUE NO ES DE RF, UN DIODO VARACTOR, PARA VALORES QUE PROPORCIONAN LINEALIDAD DE SINTONIA EN EL OSCILADOR CONTROLADO POR TENSION. EL DISCO RESONANTE O LINEA RADIAL SE SITUA SOBRE EL DIODO VARACTOR. LA LINEA RADIAL TRANSFORMA LA IMPEDANCIA DE MICROONDAS DEL DIODO VARACTOR EN UN NUEVO VALOR QUE SE ACOPLA AL CIRCUITO DE LA GUIA DE ONDA, Y POR CONSIGUIENTE AL DIODO GENERADOR DE RF. LA IMPEDANCIA DEL CIRCUITO, QUE ES FUNCION DE LA TENSION DEL DIODO VARACTOR, ACTUA DE FORMA QUE LINEALIZA LA CARACTERISTICA DE FRECUENCIA VERSUS VOLTAJE DEL DIODO VARACTOR. UNA COMPARACION DE LA OPERACION DEL CIRCUITO CON Y SIN LA LINEA RADIAL/DISCO DE SINTONIA MUESTRA UNA MEJORA DE 13 : 1 EN LA LINEALIDAD DE LA FRECUENCIA. LOS RESULTADOS EXPERIMENTALES MUESTRAN QUE LA CONFIGURACION DEL CIRCUITO DE LA PRESENTE INVENCION ES IDEAL PARA SER USADA EN OSCILADORES CONTROLADOS POR TENSION PARA MICROONDAS Y MILIMETRICAS QUE REQUIERAN UNA LINEALIDAD INHERENTE DE LA CARACTERISTICA DE FRECUENCIA VERSUS VOLTAJE. YA QUE LA LINEALIDAD DE FRECUENCIA DEL OSCILADOR CONTROLADO POR TENSION ES UN FACTOR CRITICO EN EL RENDIMIENTO DE BUCLES ENGANCHADOS EN FASE, ES ESPECIALMENTE ADECUADO PARA SER USADO EN RADARES QUE OPERAN CON ONDAS DE LAS BANDAS DE MICROONDAS Y MILIMETRICAS O EN SISTEMAS DE COMUNICACIONES QUE SON AGILES EN FRECUENCIA.-
