Abstract (Spanish)
En este artículo se presenta el diseño de dos acopladores mediante stub simple, uno en serie y otro en paralelo, y un diseño de acopladores por medio de una sección de lambda cuartos. El objetivo es comparar el comportamiento de la variación en frecuencia para un ancho de banda pasante por la línea de trans-misión, teniendo en cuenta su respectiva variación en las longitudes en las cuales se ubican los acopladores y las distancias de los stubs, de tal manera que cada diseño pueda ser comparado y analizado para determinar cuál de los tres es el mejor acople en cuanto a bajas afectaciones por un ancho de banda pasante. Para ello, se realiza cada diseño con ayuda del software “Amano-gawa” (Amanogawa.com, s. f.) y por medio de la carta de Smith. Así mismo, se realiza la simulación de cada uno y por medio de un experimento físico, stub en paralelo, se corroboran los resultados obtenidos. Se observó que el método del stub en paralelo demuestra ser el óptimo, en cuanto a implementación y aceptación en la variación de un ancho de banda más grande pasante.
Abstract (English)
his article presents the design of two couplers using a simple stub, one in series and one in parallel, and a coupler design using a quarter lambda section. The aim is to compare the behavior of the frequency variation for a passing band-width through the transmission line, considering their respective variation in the lengths in which the couplers are located and the distances of the stubs. In such a way, that each design can be compared and analyzed to determine which of all three is the best coupler in terms of low impacts due to a passing bandwidth. For this, each design is made with the help of the software Amano-gawa (Amanogawa.com, s. f.) and by means of the Smith chart. Similarly, the simulation of each one is carried out and through a physical experiment, stub in parallel, the results obtained are corroborated. Observing that the parallel stub method proves to be the most optimal, in terms of implementation and acceptance of a higher bandwidth pass-through variation
