Title (EN) POWER AMPLICATION DEVICE
(FR) DISPOSITIF D'AMPLIFICATION DE PUISSANCE
(JA) 電力増幅装置
Abstract:
(EN) A high-frequency amplifier amplifies a modulation signal or a phase modulation component of the modulation signal when outputting the signal.  A linear amplifier adds an output voltage to a power source voltage supplied to the high-frequency amplifier and amplifies a difference between the output voltage and the amplitude modulation component of the modulation signal for output.  A control signal generation unit detects the direction of flow of the output current in the linear amplification unit and generates a pulse modulation signal based on the current flow direction.  A switching amplification unit uses the pulse modulation signal as a control signal for controlling ON/OFF of the DC current so as to amplify by switch amplification the output signal of the linear amplification unit and adds the signal to a predetermined DC voltage to be supplied as a power source voltage to the high-frequency amplifier.  A DC current and a predetermined DC voltage are supplied to the switching amplification unit.
(FR) Un amplificateur haute-fréquence amplifie un signal de modulation ou une composante de modulation de phase du signal de modulation lors de la sortie du signal. Un amplificateur linéaire ajoute une tension de sortie à une tension d'alimentation fournie à l'amplificateur haute-fréquence et amplifie une différence entre la tension de sortie et la composante de modulation d'amplitude du signal de modulation pour sortie. Une unité de génération de signal de commande détecte la direction de circulation du courant de sortie dans l'unité d'amplification linéaire et génère un signal de modulation d'impulsion sur la base de la direction de circulation de courant. Une unité d'amplification de commutation utilise le signal de modulation d'impulsion comme signal de commande pour commander l'activation/désactivation du courant CC de manière à amplifier par amplification par commutation le signal de sortie de l'unité d'amplification linéaire et ajoute le signal à une tension CC prédéfinie à fournir comme tension d'alimentation à l'amplificateur haute-fréquence. Un courant CC et une tension CC prédéfinie sont envoyés à l'unité d'amplification de commutation.
(JA)  高周波増幅器は、変調信号またはその位相変調成分を増幅して出力する。線形増幅器は、出力電圧を高周波増幅器に供給する電源電圧に加算すると共に、該出力電圧と変調信号の振幅変調成分との差を増幅して出力する。制御信号生成部は、線形増幅部の出力電流が流れる方向を検知し、その電流の向きに応じたパルス変調信号を生成する。スイッチング増幅部は、パルス変調信号を制御信号に用いて、直流電流の導通および非導通を制御することで線形増幅部の出力信号をスイッチング増幅し、所定の直流電圧と加算して高周波増幅器へ電源電圧として供給する。スイッチング増幅部には直流電流および所定の直流電圧を供給する。
