Abstract

Ponte radio digitale per la trasmissione dei dati ad elevata capacità in ambienti a riflessione multipla, come aree urbane, interni di fabbricati, ecc., in grado di essere utilizzato come:- rete di radio telefoni;- rete locale per collegare calcolatori.Esso è costituito da un trasmettitore standard e da un ricevitore a sua volta costituito da un'antenna (1), da un circolatore (2), da un filtro passa banda (3), da un amplificatore LNA (4), da un gruppo convertitore di frequenze (5,6 e 12), da un amplificatore con AGC, da un buffer (8) da un banco di filtri adattati (9), da un amplificatore compensatore perdite filtro (13), da un rivelatore quadratico (14), da un combinatore percorsi (15) da un amplificatore video, (16) da un generatore di soglia adattato (17), da un banco di comparatori (18), da un blocco decisionale (19) (essenzialmente formato da un multiplexer) da un rigeneratore di tempi (20), da un allarme (21).Esso si colloca nel campo delle telecomunicazioni a microonde, per applicazioni civili e militari.
