    • Data from the orthogonal data generator is quantized by the vector data converter to become, for example, a binary value of 0 and a real number in magnitude. The output of the vector converter is modulated by the modulator, and is inputted to the amplifier. In the amplifier, the envelope of the signal to be inputted is quantized. That is, the signal of a constant envelope becomes a signal which is turned ON and OFF, so that a highly efficient nonlinear amplifier can be used. The filter removes the quantization noise generated in the vector data converter and then the signal of a low distortion and a low noise is outputted from the output terminal. The isolation unit is connected between the amplifier and the filter, avoiding effects on the output impedance of the amplifier from the filter, so that a signal of a low distortion can be outputted.
    • 来自正交数据发生器的数据由矢量数据转换器量化,成为例如二进制值0和实数数值。 矢量转换器的输出由调制器调制,并被输入到放大器。 在放大器中,对要输入的信号的包络进行量化。 也就是说,恒定包络的信号变成ON和OFF的信号,从而可以使用高效的非线性放大器。 滤波器去除矢量数据转换器中产生的量化噪声,然后从输出端输出低失真和低噪声的信号。 隔离单元连接在放大器和滤波器之间,避免了滤波器对放大器的输出阻抗的影响,从而可以输出低失真的信号。
