限幅器和某些丙类调谐放大器的线路(如图一)大致相同,它们都具有自生偏压的栅极负载阻抗和阳极调谐回路,而且大都采用锐截止的高频五极放大管,因此它们的性能和分析方法也大致相仿。限幅器所以能够具有限幅特性的主要因素,是因为限幅器具有它的特殊工作条件。如何合理地选择此种工作条件,从而使限幅器具有平坦的限幅性能是本文即将讨论 Limiter and some Class C tuned amplifier circuit (Figure 1) are roughly the same, they have a spontaneous bias gate load impedance and anode tuning loop, and most of the sharp-cut high-frequency five-pole amplifier tube, so Their performance and analytical methods are roughly the same. Limiter so it can have the limiting factor of the main factor is because the limiter has its special working conditions. How to choose such operating conditions reasonably so that the limiter has a flat limiter performance is discussed in this article
