Aplicación de métodos matriciales de síntesis en el diseño de filtros de microondas.

Abstract

The present work describes the application of matrix synthesis methods in the design of microwave filters. The theoretical foundations of microwave filters, their classification and their design stages are studied. Different synthesis methods are analyzed with special emphasis on matrix methods. The design of two Chebyshev band-pass filters based on microstrip technology is proposed, applying synthesis methods from the NxN and N + 2 coupling matrix, the latter case, in its folded canonical form. The validation and simulation of the prototypes was carried out with the assistance of professional software for the design of structures at high frequencies. In this work the Exploratory method is used to delve into the state of the art of matrix synthesis methods in filter design, with which the information obtained is analyzed using the Descriptive method to be used in the design of bandpass filters. Chebyshev in microwave applications. Furthermore, the research applies the Empirical-Analytical paradigm and a Quantitative approach with mathematical operations to characterize the studied techniques and to carry out the designs. This research is Experimental because the investigated parameters are manipulated to obtain the best characteristics in the design to achieve the established specifications.
