Abstract

Un dispositivo di comunicazione (1), per reti locali di computer del tipo cordless, impiega un modulatore (MOD) in grado di effettuare una modulazione FSK, dei dati da trasmettere (DDI), con caratteristiche ottimali grazie ad uno svitch digitale (SW), pilotato dai dati (DDI), il quale commuta in trasmissione due frequenze fisse, ricavate da un oscillatore al quarzo (OSC), in associazione ad un filtro del tipo ad onde acustiche superficiali (SAW). Il dispositivo (1) permette un notevole grado di integrazione circuitale ed è semplice e poco costoso.(Figura 3).
