Attenuatore fisso a media potenza

In alcuni moduli o sistemi RF l'attenuatore riduce la potenza di uscita senza alterare la forma d'onda o i dati del segnale, quando la potenza in uscita è troppo elevata e potrebbe danneggiare il sistema o le apparecchiature. L'attenuatore non solo migliora l'adattamento di impedenza e la affidabilità del circuito, ma può anche adattare il livello tra due circuiti o dispositivi diversi. Psatek fornisce attenuatori fissi da 1 W a 500 W, con gamma di frequenza da DC a 67 GHz e vari connettori disponibili. Contatta il team vendite (sales@psatek.com) per un preventivo.
