摘要
本文介绍一种带宽为5～8MHz,调谐范围在350～510MHz的同轴腔带通滤波器。详细地介绍了腔间孔耦合理论。给出消除耦合环自感影响的方法及减弱电耦合的途径,並给出了实测结果与理论计算的比较。
In this paper a coaxial cavity filter which possesses the bandwidth 5～8MHz and the tuning range 350～510MHz has been introduced. The coupling theory of aperture between two cavities is described in detail. This paper also gives the method for weakening coupling hoop inductance and the electrical coupling and compares the measurement results with the theoretical calculation.
