【摘要】 本文通过将威尔金森功分器核心四分之一波长转换电路等效成低通滤波器再将其与带阻滤波器级联,设计了一种具有谐波抑制功能的小型化功分器。该功分器可减小系统成本并且可以提高系统的性能。功分器工作频率为2.4GHz时,在信号二次和三次谐波处抑制分别为达到31d B和59d B,四次谐波抑制为30d B,五次谐波抑制为20d B。功分器实物测试与仿真结果吻合。功分器各个端口反射良好且输出端口实现良好隔离。更多还原

【Abstract】 In this paper, a miniature power divider with harmonic suppression function is designed by cascading the 1/4 wavelength conversion circuit of Wilkinson power divider into low pass filter. The power divider can reduce the system cost and improve the performance of the system. When the working frequency of the power divider is 2.4GHz, the suppression of signal at the second and third harmonic frequency is 31 d B and 59 d B, respectively. The suppression of signal at the fourth and fifth harmonic frequency is 30 d B and 20 d B, respectively. It is found that the simulation results are in agreement with the measured results. Each port of the power divider is well reflected and the output port is well isolated.更多还原
