We must give great care upon transistor biasing. 我们必须十分重视晶体管的偏置。
The parasitic capacitor of transistor, matching network, biasing circuit and duty cycle are the key factors to the performance of PA. Based on the analysis above, this paper has done a great deal of research and discussion of the E-type PA in detail. 影响其性能的关键因素主要有晶体管寄生电容、匹配网络、偏置电路、开关占空比等。本论文就上述课题对E类功率放大器进行详细的研究和讨论。
