摘要:
对UWB功分器进行了研究,研制了一个工作频段在3.75～9.5 GHZ的宽带功分器,该功分器通过安装一对双阶梯阻抗和平行耦合线为对称的两个输出端.实现了功分器频带的展宽.这种功分器只有一个隔离电阻,减少了隔离电阻对功分器隔离度的影响.仿真结果表明,功分器在如此宽的频带范围内仍能满足良好的性能指标,在3.75 ～9.5 GHZ频带范围内,隔离度均在-10 dB以下,输入、输出端口均达到良好的匹配.实现UWB的小型化,提高了频带的展宽,降低了加工难度.
Abstract:
The UWB power splitter has been studied, and a broadband power splitter with a working frequency range of 3.75-9.5 GHZ has been developed. The power splitter is equipped with a pair of double-stepped impedance and two symmetrical output terminals of parallel coupling lines. Realized Broadening the frequency band of the power divider. This kind of power divider has only one isolation resistor, which reduces the influence of the isolation resistance on the isolation of the power divider. The simulation results show that the power divider can still meet good performance in such a wide frequency range. In the 3.75-9.5 GHZ frequency range, the isolation is below -10 dB, and the input and output ports are well matched. It realizes the miniaturization of UWB, improves the broadening of the frequency band, and reduces the difficulty of processing.
