摘要
采用遗传算法设计了一个二节0λ/6传输线阻抗匹配器.该阻抗匹配器能在基频率及其二次谐波2个波段对任意电阻性负载实现理想的阻抗匹配,得到了阻抗匹配器的设计参数和一个修正的设计公式.数值计算结果表明,用修正公式设计的阻抗匹配器,在2<K<40范围内,驻波比全都小于1.08.
A two-section 1/6 wavelength impedance transformer is designed by genetic algorithm. It can perfectly match any resistive load at a fundamental frequency and its first harmonic. The design parameters of the dual-band impedance transformer and a revised design formula are obtained. The standingwave ratio in line all is smaller than 1.08, for 2〈K〈40.
