摘　　要：讨论了双频阻抗变换器的设计方法 ,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 ,通过对两节传输线匹配方程的严格解 ,得到了双频阻抗变换器的精确设计公式 ,对用该方法设计的阻抗变换器性能进行了仿真分析 ,仿真结果显示了该方法的有效性 ,其结果可用于实际的设计问题。The design method of a dual-band impedance transformer witch can perfectly match any resistive load at two arbitrary frequencies is discussed in this paper. The accurate design formula is obtained by solvng transcendental transmission line equations for two sections. The performance of the impedance transformer is analyzed by simulation. The result shows the validity of this method. And it can be used to practical design. [
