Diseño e implementación de un set de baluns de altas frecuencias utilizando tecnologías Microstrip y MMIC para el Laboratorio de Comunicaciones y Microondas en la FIE-ESPOCH.

Abstract

The objective of the degree work was to design and implement a set of high-frequency baluns using Microstrip technologies and Microwave Monolithic Integrated Circuits (MMIC) for the communications and microwave laboratory at the Faculty of Informatics Science and Electronics of the Chimborazo Polytechnic Higher School. After research to determine the impact of the implementation of the balun set, an experimental statistical method was designed to determine the effect of the electrical performance of Rogers material RO4350B and RO4003C, data that were processed with Statgraphics Centurion software, which helped in the choice of material. Two baluns designs were made with Microstrip technology and 2.4 GHz simulation with Ansoft Designer software, thus implementing five such devices. The same software carried out the design of the tracks and the implementation of five baluns of (2 to 7) GHz and five baluns of (5.5 to 13.5) GHz, with MMIC technology. A total of fifteen devices are deployed. The results of the research on the impact of the implementation of the devices were satisfactory. Rogers RO4003C material was chosen for design and implementation, for its high electrical efficiency and high frequency performance. Measurements were performed with the Anritsu MS3692C spectrum analyzer, injecting the signal into the baluns input with the Anritsu MS3692C signal generator, data that was processed with Matlab Software. The devices worked at the proposed frequencies, obtained the required phase variation in the output, low insertion losses and low amplitude imbalance. In conclusion, the results were as expected. It is recommended to use the right material for the implementation of high frequency devices and different disclosure techniques for printed circuits.
