摘　　要：使用射频电子设计自动化（EDA）模拟软件先进设计系统（ADS）建立电感耦合谐振器电路仿真模型,设计出一种高性能的数字调谐LC带通滤波器。选择高品质因数（Q）值的射频元器件,在合理的驱动电路控制下,在30~110 MHz频率范围内该滤波器能实现10μs内的频率调谐,并具有良好滤波器宽带电性能。实验表明,该滤波器的电性能测试数据与仿真结果吻合。By using the RF EDA simulation software ADS to establish the inductance-coupllng resonator circuit model, a high performance digitally tunable frequency-hopping I.C band-pass filter is designed in this work. By choosing high O factor RF elements controlling under right driving circuit, the filter can realize frequency hopping at a rate of speed less than 10 [xs between 30 MHz and 110 MHz and has good wide-band performance. Experiment in- dicates that the testing data of the filter sample is consistent with the emulating result.
