摘要
提出了采用固定电感的ＬＣ滤波器的制作方法。为了弥补固定电感值与设计值之间的误差和精确地考虑电感器的寄生参量，文章将电路优化技术推广到有耗滤波器的设计之中，并且建立了电容器的自动配对系统，避免了复杂的调试过程，降低了生产成本，实现了滤波器的小型化。
The Method of making LC filters with small-fixed inductors is presented.To remedy thedifference between the designed value and the fixed inductance and consider accuratly the influ-ence of stray parameters of the inductors,the circuit optimization technigue is extended intoiossy filter design.The auto-pairing system of the capacitors is set up,the complex adjustmentof the filters is avoided,the production cost is reduced and LC filter miniaturization isachieved。
