| 摘 要： | 阻抗匹配技术在微波工程中十分重要。分析了四分之一波长阻抗变换器的T形等效电路,从而得到了双波段阻抗变换器的设计公式。利用该等效电路,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,以实现2个任意的频率点对任意电阻性负载实现理想的阻抗匹配。对该方法设计的阻抗变换器性能进行了仿真分析,结果显示该方法适用于工程应用。

| Abstract: | The T shape equivalent circuit of the λ0/4 impedance transformer is analyzed,and the dual-band impedance transformer design formula is obtained.This equivalent circuit can facilitate transforming of the λ0/4 impedance transformer at single frequency into dual-band.By this way,it can make witch perfectly match any resistive load at two arbitrary frequencies.The performance of the impedance transformer by this method is simulated and analyzed.Results show that it can be adaptable to engineering applications. |
