摘要
本文详细地研究了调谐微波滤波器的腔间耦合结构对其调谐范围、通带宽度的影响.文中分析了圆孔耦合结构的特点,指出了其对调谐范围的限制以及传统公式存在的问题,提出了腔间的矩形孔耦合结构,建立了侧面孔的等效电路模型,推导了矩形孔的设计公式.
The effect on the tuning- width and the bandwidth of tunable microwave filters by their intercavity coupling structures was researched in detail in this paper. The limit for tuning- width was pointed out and the problem in traditional method was found. The equivalent circuit of a side hole was set up. A rectangular hole as a interstage coupling structure was put forward and its designing formula was gaven.
