| 摘 要： | 针对同轴介质滤波器有限传输零点不易实现的问题,介绍了一种新颖的带陷波特性的介质带通滤波器,由1/4波长的同轴介质谐振器相互耦合,并在任意入出端级联一段吸收网络组合优化而成。该网络在通带外边缘既产生了有限传输零点,又增加了滤波器节数,且可灵活设计零点的位置,对特定的频率进行吸收,具有易装配、易调试、工程实用化强的特点。实例制作的中心频率1.0 GHz、3 dB带宽约30 MHz,50 dB陷波频点975 MHz,仿真设计和实测结果吻合很好。

| Abstract: | It is difficult for the coaxial dielectric filter to achieve finite transmission zero.A novel coaxial dielectric band-pass filter with notched speciality was introduced to solve the problem.The filter includes 1/4 wavelength coaxial dielectric resonators coupled each other and a absorbed network which is connected to the input port or the output port.The network brings the finite transmission zero and increases the number of sections,and the position of the zero can be placed neatly to absorb the special fr... |
