Abstract in Spanish

Hoy en día los sistemas de comunicaciones se encuentran omnipresentes en virtualmente todos los aspectos de la vida cotidiana. Sea inalámbrico o no, requieren indispensablemente filtros de radiofrecuencia y microondas en las diferentes etapas de los receptores y transmisores que los conforman. Una clase de filtro, denominado Pasabanda es de particular importancia para el funcionamiento de las cadenas de recepción y transmisión. La presente tesis tiene como objetivo explorar el diseño de filtros pasabanda reconfigurables en frecuencia. Para ello se analizarán las diferentes tecnologías de ajuste de frecuencia, con una sólida base teórica para la tecnología planar que emplearemos. Seguiremos con un estudio de la razón por la cual resultan ser difíciles de sintetizar y a continuación una solución práctica para atacar el problema de a partes. Se analizarán los mecanismos por los cuales se apartan del caso teórico ideal y los métodos para mejorarlos. Cinco filtros pasabanda se diseñarán, simularán, fabricarán, y caracterizarán en dos bandas en el rango de las microondas: Banda L y Banda C, cada uno mejorando sobre el diseño anterior. Alcanzar los 7 GHz de frecuencia central representó un desafío que logramos luego de mucho esfuerzo y aprendizaje. Finalizamos con los lineamientos para trabajos futuros de mayor complejidad.

Abstract in English

Nowadays communications systems are ubiquitous in virtually all aspects of everyday life. Whether wireless or otherwise, they certainly require radiofrequency and microwave filters in the different stages of the receivers and transmitters that incorporates them. One kind of filter, called Bandpass, is of particular importance for the operation of receive and transmit chains. This thesis aims to explore the design of frequency reconfigurable bandpass filters. To this end, the different frequency adjustment technologies will be analyzed, with a solid theoretical basis for the employed planar technology. We will continue with a study of the reason why they are difficult to synthesize and afterwards a practical solution to attack the problem piecewise. The mechanisms by which they step aside from the ideal theoretical case and the methods to improve them will be analyzed. Five bandpass filters will be designed, simulated, manufactured, and characterized in two bands in the microwave range: L-Band and C-Band, each one improving on the previous design. Reaching the 7 GHz central frequency represented a challenge that we achieved after much effort and learning. We end with the guidelines for future work of greater complexity.
