摘　　要：本文介绍了一种电调微带线滤波器的设计方法。通过仿真计算得到了外部耦合系数与抽头对地距离的关系曲线。利用电路仿真软件ADS对整体实际模型进行了仿真和优化。设计了一种调谐范围为1-1.5GHz、插入损耗小于5dB、相对带宽4%的电调谐微带线滤波器。The design of electronically tunable microstrip filter is introduced in the paper. The relation curve of the external coupling coefficient to the distance above ground is gotten by simulation. Simulation and optimization are made by use of software ADS. An electronically tunable filter is designed with tuning .frequency range of 1-1.5 GHz, insertion loss of less than 5 dB and relative bandwidth of 4%.
