【摘要】：采用周期性慢波结构加载的开路传输线代替传统的四分之一波长阻抗变换器,设计一种小型化且适用于高频的Wilkinson功分器,有效改善了传统Wilkinson功分器尺寸大且高频时容易出现色散的问题。最后基于FR4基板,设计应用于900 MHz的Wilkinson功分器,测量结果显示,三个端口匹配良好,S11约为-20.58 dB,S22约为-23.62 dB,S21约为-3.28 dB,输出端口的隔离度约为-33.3 dB,仿真结果和测量结果趋势吻合,验证了该方法的可行性。
[Abstract]:An open circuit transmission line loaded with periodic slow-wave structure is used instead of the traditional 1/4 wavelength impedance converter to design a miniaturized and high frequency Wilkinson power divider.It can effectively improve the dispersion problem of the traditional Wilkinson power divider with large size and high frequency.Finally, based on the FR4 substrate, a 900 MHz Wilkinson power divider is designed. The measurement results show that the three ports match well, the S11 is -20.58 dBU S22 is about -23.62 dBU S21 is -3.28 dB, the isolation of the output port is about -33.3 dB, and the simulation results are consistent with the measurement results.The feasibility of the method is verified.
