Il passaggio dal silicio ai semiconduttori a banda larga (nitruro di gallio, carburo di silicio e altri) consente di aumentare significativamente le frequenze operative e migliorare l'efficienza delle soluzioni. Pertanto, uno dei settori promettenti per l'applicazione dei chip e dei transistor a banda larga \u00e8 la comunicazione e i radar. L'elettronica basata su soluzioni GaN offre un incremento della potenza e un'estensione della portata dei radar, un vantaggio immediatamente sfruttato dai militari.<\/p>\n

\"L'esercito<\/p>\n

Lockheed Martin ha annunciato<\/a><\/noindex>, che le prime unit\u00e0 radar mobili (RLS) basate su elettronica con elementi in nitruro di gallio sono state fornite alle forze armate americane. L'azienda non ha introdotto nulla di nuovo. Le RLS di controbatteria AN\/TPQ-53, adottate in armi dal 2010, sono state trasferite alla base di elementi GaN. Questo \u00e8 il primo e attualmente unico radar al mondo basato su semiconduttori a banda larga.<\/p>\n

Grazie all'adozione di componenti GaN attivi, il radar AN\/TPQ-53 ha aumentato la portata di rilevamento delle posizioni d'artiglieria nascoste e ha ottenuto la possibilit\u00e0 di monitorare simultaneamente le minacce aeree. In particolare, il radar AN\/TPQ-53 \u00e8 stato utilizzato anche contro i droni, inclusi quelli di piccole dimensioni. L'individuazione delle posizioni d'artiglieria nascoste pu\u00f2 avvenire sia in un settore di 90 gradi che con una visione circolare a 360 gradi.<\/p>\n

Lockheed Martin \u00e8 l'unico fornitore di radar con Fase Array Attiva (AESA) per le forze armate statunitensi. L'adozione di una base di componenti GaN le consente di prevedere un ulteriore decennio di leadership nel miglioramento e nella produzione di sistemi radar.<\/p>\n
