摘　　要：文章设计了一种双频带调谐电路,可以在特定频点呈现出开路、短路特性,其结构简单,并可通过调节电路中参数实现两个频带独立可控谐振。该电路共产生三个传输零点,零点的位置由调谐电压确定,改善了阻带抖裙特性且通带间互不影响,电路的最大插入损耗小于0.5dB。In this report,a dual-band tuned circuit is designed,which can exhibit open circuit and short circuit characteristics at specific frequency points.It has a simple structure and can realize independent controllable resonance of two frequency bands by adjusting parameters in the circuit.The circuit generates three transmission zero points,and the position of the zero points can be changed correspondingly with the change of the tuning frequency,which improves the characteristics of the stop band and the mutual influence between the pass bands.The maximum insertion loss of the circuit is less than 0.5dB.
