Resumen

Este artículo presenta métodos para obtener circuitos equivalentes de ánodos de magnetrón mediante análisis de resonadores RLC, y posteriormente crear plantas adecuadas para el diseño de sistemas de control. Se describen dos enfoques complementarios: la extracción de parámetros del circuito equivalente a partir de la admitancia, que se obtiene de medidas de parámetros de dispersión, y el análisis de modo propio, que permite la extracción directa de las características del resonador a partir de campos electromagnéticos simulados. La validez de estos métodos se demuestra mediante su aplicación a una cavidad resonante cilíndrica simple. Posteriormente, estos métodos se aplican al análisis de un ánodo de magnetrón de 10 cavidades, demostrando cómo los parámetros del circuito equivalente dependen de la geometría del dispositivo. Los resultados obtenidos permiten modelar el comportamiento electromagnético del ánodo del magnetrón mediante un circuito equivalente, que a su vez facilita el estudio de estos dispositivos y el diseño de sistemas de control.
