Comtech Banda Ka 280W 27.5-30 GHz Comtech
La familia de amplificadores SuperCoolTM tiene muchas ventajas prácticas sobre los amplificadores enfriados por aire tradicionales, incluida la carga de calor reducida en los concentradores; instalación flexible y más compacta; facilidad de servicio y mantenimiento; mayor confiabilidad; reducción de ruido ambiental; y ganar estabilidad sobre la temperatura ambiente.
El nuevo diseño de Comtech Xicom incorpora canales de enfriamiento integrados en la placa base del amplificador, externos al compartimiento sellado de alta tensión y circuitos de RF, con conexiones antigoteo. La eliminación de la necesidad de provisión de flujo de aire simplifica drásticamente la disposición y el diseño del concentrador y brinda más espacio para operaciones de mantenimiento y equipos adicionales.
