摘　　要：分析和研究了螺旋滤波器对于电磁波的影响以及衰减因数和滤波器品质因数的关系,并详细探讨了螺旋滤波器的设计方法,最后采用平行五腔的横向螺旋线耦合结构设计并实现了一种用于有线电视系统的高功率窄带滤波器。测量结果证实了仿真结果的可靠性和实用性。In this paper, the electromagnetic wave effect on spiral filter and its relationship with loss gene and filter value Q are analyzed and studied. The designing method of spiral filter is briefly discussed. A high power 5-cavity VHF helical filter used in cable TV system is designed and realized in this paper. The simulated result proves its reliability and practicability.
