资料介绍

针对传统多调谐无源滤波器体积庞大、占地面积大的问题,提出一种考虑各线圈之间耦合作用的紧凑型多调谐滤波器的设计方法。从阻抗函数出发,得到了传统多调谐无源滤波器的电路实现形式,建立了与该电路相等效的各电感之间具有耦合关系的电路。通过耦合电感的解耦以及与传统滤波器电路的等效关系,列写出关于线圈几何参数的非线性方程组,求解得到一台线圈同轴放置的紧凑型三调谐滤波器的设计结果。对设计的紧凑型滤波器进行了仿真研究并制作了实验样机,仿真和实验结果表明这种结构的多调谐滤波器减小了线圈组的占地面积同时也具有良好的滤波性能。

Aiming at the problem of large volume and large floor space of traditional multi-tuned passive filters, a design method of compact multi-tuned filter considering the coupling between coils was proposed. Starting from the function of complex impedance, the circuit form of the traditional multi-tuned passive filter was obtained, and the circuit with the coupling relationship between the inductors equivalent to the former was established. Through the decoupling of the coupled inductor and the equivalent relationship with the traditional filter circuit, the nonlinear equations of the coil geometric parameters were established, and the design result of the compact three-tuned filter with coils coaxially placed was obtained. The simulation of the designed compact filter was carried out and the experimental prototype was fabricated. The simulation and experimental results show that this compact multi-tuned filter reduces the area occupation of the coils and also has good filtering performance.
