Egatel acudir como cada a o a NAB, para presentar sus ltimas novedades en transmisores de televisi n. En su stand, podremos ver los nuevos transmisores UHF de alta eficiencia en Banda Ancha (Serie WHET). La soluci n Doherty es por primera vez Banda Ancha, lo que significa que es aplicable a toda la banda UHF y no ser necesario que los operadores hagan ning n cambio ni modificaci n en los amplificadores ante un cambio de canal.
Como ejemplo de la Serie WHET, se exhibir un transmisor de 3KW DVB/ISDB (4KW ATSC), modelo TLWH7804. El equipo de refrigeraci n l quida se caracteriza por su dise o completamente modular e incluye un sistema de bombas integrado en el mismo rack que el transmisor. Esta soluci n optimiza la inversi n y el dise o de nuestras instalaciones.
En refrigeraci n por aire se presentar y se realizar n demostraciones en funcionamiento real con el amplificador Doherty de 600 Wrms DVB/ISDB (700Wrms ATSC), modelo AUH601, con el que se pueden llevar a cabo integraciones de hasta 5 amplificadores por rack, alcanzando potencias pr ximas a 3 kW en DVB/ISDB (3,5KW en ATSC), con un rendimiento energ tico inmejorable. El dise o de estos amplificadores incluye aspectos que sintetizan todo el know-how de Egatel, evitando la circulaci n de aire por placas o componentes, redundando fuentes de alimentaci n extra bles por el frontal o disponiendo los ventiladores en la parte exterior para una sencilla sustituci n sin necesidad de abrir el m dulo.
La tecnolog a Doherty aplicada en los amplificadores proporciona un rendimiento de hasta un 42%, optimizando significativamente el consumo energ tico y, por tanto, los costes de operaci n.
Con independencia de la potencia o sistema de refrigeraci n utilizado, Egatel ofrece sus moduladores en dise os de 1U 19 para los est ndares DVB-T/-H/T2, ISDB-T/TB y ATSC, cumpliendo con los m s altos par metros t cnicos de calidad. La precorrecci n digital adaptativa se ofrece de serie en todas las configuraciones, facilitando la operaci n y el mantenimiento, y con el uso de programas de control basados en servidores web embebidos, memorias extra bles con inserci n frontal para la carga y descarga de configuraciones, opciones de monitorizaci n de la RF,
Finalmente es de destacar la consolidada oferta de Egatel en soluciones de reemisores en bajas potencias, permitiendo trabajar igualmente en cualquier est ndar y con las m s altas prestaciones en canceladores de ecos din micos.
