摘　　要：讨论了双波段阻抗变换器的设计方法,分析了四分之一波长阻抗变换器的∏形等效电路,得到了双波段阻抗变换器的设计公式。利用该等效电路,能方便将单频工作方式的四分之一波长阻抗变换器转变为双波段工作方式。对用该方法设计的阻抗变换器性能进行了仿真分析。结果显示,该阻抗变换器能在两个任意的频率点对任意电阻性负载实现理想的阻抗匹配。The design method of the dual - band impedance transformer is discussed in this paper. The I1 shape equivalent circuit of the λ0/4 impedance transformer has analyzed, and the dual-band impedance transformer design formula is obtained. Using this equivalent circuit, can facilitate transforms rhe λ0/4 impedance transformer at single frequency into dual-band. The performance of the impedance transformer by this methods design is simulation analyzed. The result has shown witch can perfectly match any resistive load at two arbitrary frequencies.
