所描述的新型放大器基于负载网络，该负载网络被合成为具有瞬态响应，该瞬态响应即使在有源器件切换时间是交流电压的很大一部分的情况下也使功率效率最大化。周期新的一类放大器，命名为“E类”，定义和说明的详细说明和一组设计方程的一类简单的成员。对于该电路，作者测量了一对Motorola 2N 3735 TO-5晶体管在3.9 MHz和26 W输出下的96%晶体管效率。E类的优点是效率非常高，先验的可设计性，二次击穿应力的大幅降低，对有源器件特性的敏感性低，以及在比以前公布的D类电路更高的频率下的高效率操作的潜力。
The new class of amplifiers described is based on a load network synthesized to have a transient response which maximizes power efficiency even if the active device switching times are substantial fractions of the a.c. cycle. The new class of amplifiers, named `Class E,' is defined and is illustrated by a detailed description and a set of design equations for one simple member of the class. For that circuit the authors measured 96 percent transistor efficiency at 3.9 MHz at 26-W output from a pair of Motorola 2N3735 TO-5 transistors. Advantages of Class E are unusually high efficiency, a priori designability, large reduction in second-breakdown stress, low sensitivity to active-device characteristics, and potential for high-efficiency operation at higher frequencies than previously published Class-D circuits.
