晶体管连续工作模式的提出和提出，为实现宽带(接近一个倍频程)的高效率功率放大器(PA)提供了一条替代的设计路线。连续模式的表述为扩展基波/谐波阻抗空间提供了数学框架，在该空间上可以保持传统功放模式的功率和效率性能，即，类、B、类F等。该数学框架已通过射频I-V波形工程测量系统和演示功放样机的实现进行了实验验证。
The introduction and formulation of the "Continuous" modes of transistor operation has provided an alternative design route for the realization of high efficiency power amplifiers (PA's) over a wide bandwidth (approaching an octave). The formulation of the "Continuous" modes provides a mathematical framework for extending the fundamental/harmonic impedance space over which the power and efficiency performance of the traditional PA modes, i.e. Class, B, Class F, etc, can be maintained. This mathematical framework has been experimentally validated using RF I-V waveform engineering measurements systems and the realization of demonstrator PA prototypes.
