| 摘 要： | 介绍了一种高隔离度微带双工器的设计方法。该双工器由2个在通带附近具有一对传输零点的微带带通滤波器组成。分析了具有传输零点带通滤波器的设计方法，给出了中心频率为1．85GHz，分数带宽为10．5％和中心频率为2．15GHz，分数带宽为9％的微带开路环带通滤波器设计实例。利用微波CAD软件对连接双工器T型接头的微带尺寸进行了优化，仿真结果表明该双工器具有较好的频带响应及隔离度。

| Abstract: | A design method of micro-strip open loop diplexers with good isolation is presented. The micro-strip diplexers are made up with two highly selective micro-strip bandpass filters, which have a pair of transmission zeros between the pass bands. In the paper, the design method of micro-strip open loop bandpass filter is introduced, and one example of filter with 1.85 GHz center frequency, 10.5% fractional bandwidth and the second one with 2.15 GHz center frequency, 9% fractional bandwidth are given. With the aid of microwave CAD software, the value of T conjunction micro-strip line of diplexers is optimized. The result of simulation shows the microstrip open loop diplexers has excellent frequency response and high isolation. |
