| dc.description.abstract | En este documento se presentan el análisis y los resultados relevantes relacionados con la caracterización de los conectores SMA acoplados a una línea de transmisión de 50 Ω. Dicha caracterización se llevó a cabo utilizando un analizador de espectros FSH8 Rohde & Schwarz, con el cual se midieron dos de sus parámetros S y se compararon con el comportamiento en simulación de la línea con y sin los conectores. El error relativo obtenido en cada caso evidencia algunos de los efectos encontrados por la influencia de los conectores y permite realizar un acercamiento al comportamiento esperado en este tipo de implementación. Por otra parte, también se puede concluir que los conectores SMA aportaron un corrimiento en frecuencia de la resonancia de la línea, así como un cambio en su atenuación, también se puede establecer que una calibración adecuada y completa de los puertos del equipo que se utilice en mediciones en altas frecuencias es fundamental para la obtención de resultados correctos y para descartar fuentes de eventuales errores. De igual forma, es viable reproducir desde la simulación los principales efectos que pueden tener los conectores utilizados en una medición de radiofrecuencia. Finalmente, dado que cada conector aporta errores particulares imposibles de predecir con certeza, es necesario el uso de técnicas de procesamiento adicionales que permitan minimizar estos errores. | spa |
| dc.description.abstract | This document presents the analysis and relevant results related to the characterization of the SMA connectors coupled to a 50 Ω transmission line. The characterization was carried out by using a Rohde & Schwarz FSH8 spectrum analyzer, with which two of its S-parameters were measured and then compared with the simulation behavior of the line, with and without the connectors. The relative error obtained in each of the cases evidences some of the effects that were encountered due to the influence of the connectors, and enables a closer approach to the expected behavior in this type of implementation. On the other hand, it can also be concluded that the SMA connectors contributed to a frequency shift of the resonance of the line, as well as a change in its attenuation. It can also be established that an adequate and complete calibration of the ports in the equipment that is used for measurements in high frequency is fundamental to obtain correct results and to discard sources of possible errors. Similarly, from the simulation, it is feasible to reproduce the main effects that the connectors used in the measurement of a radio frequency can have. Finally, given that each connector contributes particular errors that are impossible to predict with certainty, it is necessary to use additional processing techniques that allow these errors to be minimized. | eng |
