Abstract: front page image
(EN)Disclosed is an amplifying circuit (1) which is provided with: an amplifier (2), which amplifies power of input signals; a power supply unit (3), which applies a power supply voltage to the amplifier (2); a temperature sensor (11), which detects the temperature of the amplifier (2); and a frequency determining unit (8), which determines the transmission frequency of the input signals. Furthermore, the amplifying circuit is provided with a control unit (10), which adjusts the power supply voltage of the power supply unit (3) and the signal power of the input signals, on the basis of the detected temperature obtained from the temperature sensor (11) and the transmission frequency obtained from the frequency determining unit (8).
(FR)L'invention concerne un circuit d'amplification (1) qui comporte: un amplificateur (2) qui amplifie la puissance de signaux d'entrée, une unité d'alimentation (3) qui applique une tension d'alimentation à l'amplificateur (2); un capteur de température (11) qui détecte la température de l'amplificateur (2); et une unité (8) déterminant la fréquence, qui détermine la fréquence de transmission des signaux d'entrée. De plus, le circuit d'amplification est pourvu d'une unité de commande (10) qui règle la tension d'alimentation de l'unité d'alimentation (3) et la puissance du signal des signaux d'entrée, sur la base de la température détectée par le capteur de température (11) et de la fréquence de transmission obtenue par l'unité (8) déterminant la fréquence.
(JA)本発明の増幅回路1は、入力信号の電力を増幅する増幅器2と、増幅器2に電源電圧を付与する電源部3と、増幅器2の温度を検知するための温度センサ11と、入力信号の送信周波数を決定する周波数決定部8とを備えている。さらに、温度センサ11から得られる検知温度、及び周波数決定部8から得られる送信周波数に基づいて電源部3の電源電圧、及び入力信号の信号電力を調整する制御部10を備えている。
