微带发夹型谐振器滤波器的实验研究

微带发夹型谐振器滤波器具有尺寸小、成本低、易于集成等优点,在微波平面电路的设计中有着良好的应用前景.此前已有一些文献对这类滤波器进行过研究,但一般都是只针对某一种特定的发夹型谐振器进行滤波器的分析设计,而没有对各种不同谐振器的性能指标与滤波器设计要求进行比较研究.本文使用几种不同的发夹型谐振器和不同耦合方式分别设计了三阶和四阶带通滤波器,通过实验对这几种谐振器滤波器进行了分析研究,得到了一些具有实际应用价值的结论.

Experimental Study on Microstrip Hairpin Resonator Filters

Microstrip hairpin resonator filters have found wide applications in microwave planar circuits and microwave integrated circuit (MIC) due to the virtues such as compact structure, low cost, easy fabrication, and easily integrated. They have been investigated by many researchers, but the work usually focused on the design of filters using a specific structure of a hairpin resonator. In this paper, several 3-pole and 4-pole bandpass filters using different hairpin resonators and different coupling schemes are investigated and compared for applications. Some useful conclusions are obtained.
