Abstract
Oggetto dell'invenzione è un dispositivo di controllo per amplificatori di potenza che aumenta il livello di potenza di un am-plificatore di potenza (203) senza un sostanziale treno di impulsi di rumore da frequenza. Il dispositivo di controllo presenta un rivelatore di potenza di uscita a radio frequenza (211) che genera un segnale (229) correlato al livello di potenza dell'amplificatore di potenza (203). Questo segnale (229) viene confrontato (215) con un segnale di riferimento (213) per determinare se l'amplificatore di potenza (203) è attivo. Il segnale (227) generato da questo comparatore (215) viene usato per determinare il livello di tensione del segnale (231) di controllo automatico di uscita (AOC).
