在无线电广播和声学工业上,需要大量的输出功率在0.5w至6w间的低频功率放大器。这种低功率放大器几乎完全是用互补线路构成,对于高功率放大器则使用类似互补线路。在类似互补——输出级中,具有相同导电率的输出级晶体管和简单的线路连接。下面阐述互补——输出级选择参数的基础。

In the radio broadcast and acoustics industry, a large number of low-frequency power amplifiers with output powers between 0.5w and 6w are required. This low-power amplifier is almost entirely composed of complementary lines, for high-power amplifiers use a similar complementary line. In similar complementary - output stage, with the same conductivity of the output stage transistors and simple line connections. The following describes the basis for complementary-output stage selection parameters.
