    • An burst-type transmission output power control apparatus, includes an open loop formed by an variable power driver (10) for amplifying a modulated wave signal (Sin), a saturation type high power amplifier (2) and a directional coupler (3). A closed loop is constructed by a variable attenuator (9), connected to the directional coupler, a detector (5) and a relative error amplifier (6) connected to the saturation type high power amplifier. A voltage converter (11) supplies a power supply voltage (Vp') to the saturation type high power amplifier so that a saturation output of the saturation type high power amplifier is raised only for a short period before and after a steady-state burst waveform, including a rising and falling time periods.
    • 突发型传输输出功率控制设备包括由用于放大调制波信号(Sin)的可变功率驱动器(10),饱和型高功率放大器(2)和定向耦合器(3)形成的开环。 闭环由连接到定向耦合器的可变衰减器(9),检测器(5)和连接到饱和型高功率放大器的相对误差放大器(6)构成。 电压转换器(11)向饱和型高功率放大器供应电源电压(Vp'),使得饱和型高功率放大器的饱和输出仅在稳态突发波形之前和之后的短时间段内升高 包括上升和下降时间段。 <图像>
