Ce nouveau circuit simplifie la conception et r\u00e9duit de fa\u00e7on significative la taille, le poids et la consommation des syst\u00e8mes radar \u00e0 commande de phase utilis\u00e9s dans les applications de d\u00e9fense, de surveillance, de contr\u00f4le du trafic a\u00e9rien, de communications et de m\u00e9t\u00e9orologie. Gr\u00e2ce au circuit ADAR1000, les concepteurs de syst\u00e8mes avioniques peuvent r\u00e9aliser des r\u00e9seaux d\u2019antennes plates, ce qui r\u00e9duit le profil des syst\u00e8mes radar traditionnels et simplifie la conception d\u2019a\u00e9ronefs plus petits et plus l\u00e9gers. Le nouveau circuit ADAR1000 fonctionne en mode plug-and-play, ce qui permet aux concepteurs poss\u00e9dant une exp\u00e9rience r\u00e9duite en technologie RF d\u2019accro\u00eetre les performances et de prolonger la dur\u00e9e de vie op\u00e9rationnelle de leurs syst\u00e8mes radar.<\/p>\n

Le circuit int\u00e9gr\u00e9 de formation de faisceaux \u00e0 antenne active ADAR1000 \u00e0 4 voies remplace 12 composants discrets habituellement utilis\u00e9s pour les contr\u00f4les num\u00e9riques et le r\u00e9glage en gain et phase de l\u2019antenne. Ce circuit prend en charge le duplexage par r\u00e9partition dans le temps (TDD) dans les bandes X et Ku, et comprend un commutateur T\/R int\u00e9gr\u00e9 qui peut \u00eatre utilis\u00e9 pour s\u00e9lectionner le port commun en tant qu\u2019entr\u00e9e pour l\u2019\u00e9mission (Tx) ou sortie pour la r\u00e9ception (Rx). Les quatre paires de canaux Tx et Rx disposent de r\u00e9glages en gain et phase programmables ind\u00e9pendamment. L\u2019ADAR1000 peut \u00eatre configur\u00e9 pour contr\u00f4ler directement tous les aspects de la commande par impulsion du module T\/R externe en utilisant un minimum de circuits suppl\u00e9mentaires. <\/p>\n

Tous les r\u00e9glages peuvent \u00eatre charg\u00e9s dans la m\u00e9moire embarqu\u00e9e afin d\u2019acc\u00e9l\u00e9rer l\u2019acc\u00e8s aux valeurs de phase et gain, ainsi qu\u2019aux r\u00e9glages du module T\/R. L\u2019ADAR1000 constitue un bloc \u00e9volutif qui permet de mettre rapidement en \u0153uvre des antennes r\u00e9seau \u00e0 commande de phase active destin\u00e9es aux syst\u00e8mes radar et de communications de nouvelle g\u00e9n\u00e9ration, sans support de conception tierce partie \u00e9tendu. <\/p>\n

\u00ab En associant le portefeuille de solutions RF le plus large de l\u2019industrie et son expertise \u00e9tendue en mati\u00e8re de conditionnement et de conception, Analog Devices aide ses clients \u00e0 mettre en \u0153uvre rapidement des antennes r\u00e9seau \u00e0 commande de phase \u00bb, a d\u00e9clar\u00e9 John Cowles, directeur g\u00e9n\u00e9ral de la division RF & Microwave d\u2019Analog Devices. \u00ab Cette nouvelle solution \u00e0 commande de phase est plus compacte, plus l\u00e9g\u00e8re, et aussi puissante qu\u2019une solution \u00e0 commande de phase classique. De plus, elle \u00e9largit l\u2019\u00e9ventail d\u2019utilisations potentielles de la technologie de commande de phase en r\u00e9duisant consid\u00e9rablement le profil de l\u2019antenne. \u00bb<\/p>\n
