Contour modulation is a technique in which a phase-modulated signal waveform and amplifier output impedance work together to maintain higher efficiency over a sizable output power back-off.
轮廓调制结合了一种相位调制信号的波形和放大器的输出阻抗，可在某个较大型输出电源关闭后保持更高的效率。
Without the minimum output power requirement in the main output just as magnetic amplifier, higher efficiency can be achieved in this circuit.
和磁开关不同，该变流器在主反馈输出上没有最小输出负载的要求，从而电路可以达到更高的效率。
The benefits of large effective area fibers are higher power handling capability for improved system signal to noise ratio (SNR), and longer amplifier spacing.
由于大有效面积非零色散位移光纤具有较高的额定最大功率，其直接效益之一就是可改善系统信噪比和加大放大器间隔。
The linearity of active stages grows with increasing current or power, i. e. The more current available for amplifier stages and for LO power for mixers, the higher the linearity of the concept.
有源器件的线性度是随着电流或功率的增加而增加的，即这样一个概念：放大器级的电流越大并且混频器的本 振功率越大，那么线性度就越高。
