Abstract

Viene rivelato un circuito per compensare un livello di uscita in radiofrequenza di un ricetrasmettitore radio portatile che comunica a duplex intero tramite una potenza di batteria. Il circuito include un dispositivo di compensazione del segnale in radiofrequenza avente un secondo amplificatore di potenza per amplificare in potenza un segnale in radiofrequenza immesso fino ad un livello di trasmissione corrispondente ad un livello di tensione di controllo di potenza automatico immesso, secondo circuito di trasmissione collegato ad un terminale di uscita del secondo amplificatore di potenza per radiotrasmettere il segnale in radiofrequenza amplificato, secondo circuito di controllo di uscita di trasmissione per fornire una seconda tensione di controllo di potenza automatico al secondo amplificatore di potenza in risposta alla tensione di ingresso del livello di uscita predeterminato, una seconda batteria e secondo circuito di comando di potenza per regolare la seconda tensione di batteria alla tensione del livello predeterminato a fornire la tensione regolata come una tensione operativa delle unità rispettive nel dispositivo di compensazione del segnale in radiofrequenza e un circuito di collegamento per collegare la tensione di livello di uscita predeterminato al secondo circuito di controllo di uscita di trasmissione e collegare una uscita del primo circuito trasmittente ad un ingresso del secondo amplificatore di potenza e, allo stesso tempo, fornire un segnale di rivelamento e di collegamento al primo circuito di controllo di uscita di trasmissione.
