A novel miniaturized ultrawideband reconfigurable power divider based on slotline and double-sided parallel-strip line (DSPSL) is presented in this article. The switch from the two-way out-of-phase power divider to the four-way in-phase power divider can be realized by using only two PIN diodes in the presented power divider, which will simplify greatly the circuit design and reduce the cost. Two working states in different transmission modes can be switched under the different bias conditions of the two PIN diodes. The equivalent-circuit model is developed to analyze the presented power divider. An ultrawideband reconfigurable power divider is designed and fabricated. At the four-way in-phase power-dividing mode, the measured insertion loss is less than 2.15 dB, the output isolation is greater than 15 dB, and the relative bandwidth is about 59.3%. At the two-way out-of-phase power-dividing mode, the measured insertion loss is less than 1.8 dB, and the relative bandwidth is about 57.1%.

本文提出了一种基于槽线和双面平行带线（DSPSL）的新型小型化超宽带可重构功率分配器。该功分器仅使用两个PIN二极管即可实现两路异相功分器到四路同相功分器的切换，大大简化了电路设计并降低了成本。两个PIN二极管在不同的偏置条件下可以切换不同传输模式的两种工作状态。开发等效电路模型来分析所提出的功率分配器。设计并制造了一种超宽带可重构功率分配器。在四路同相功分模式下，测得插损小于2.15dB，输出隔离度大于15dB，相对带宽约为59.3%。在两路异相功分模式下，测得插入损耗小于1.8 dB，相对带宽约为57.1%。
