恒幅载波以一种特殊的方式进行相位调制，使得频谱包含待放大信号的副本。载波驱动放大器（如果需要的话，达到饱和），而可以等于峰值放大器功率的副本由一个简单的滤波器选择。原则上，存在绝对线性。同样的技术可以使具有幅度失真的信号路径线性化。
A constant amplitude carrier is phase modulated in a special way so that the spectrum contains a replica of the signal to be amplified. The carrier drives an amplifier (to saturation, if required) and the replica, which can equal the peak amplifier power, is selected by a simple filter. In principle, there is absolute linearity. The same technique can linearise a signal path with amplitude distortion.
