摘要
微带发夹型滤波器结构紧凑、易于制造 ,在微波低频端广为应用。以前的设计公式都没有考虑滑动因子θ的影响 ,文中推导给出了在考虑滑动因子θ影响的情况下发夹型滤波器的设计公式 ,介绍了抽头线位置的确定方法 ,提高了抽头线发夹型滤波器设计初始值的精确度。
Microstrip hairpin filter has been widely used in the lower microwave frequencies for its compact structure and easiness of manufacture. The hairpin filter design formula, which takes the slide factor θ into account, is deduced and presented in this paper. The tapped line location is also presented. The initial design is more accurate than before.
