微波滤波器综合的出发点在于滤波函数的选择,滤波函数的性质决定了滤波器的响应。文中提出了一种广

义的巴特沃思滤波函数,在保留其群时延上优势的同时,通过引入有限位置的传输零点,大大的改善巴特沃思函数的带外

特性,使得其可以适应现代通信技术对微波滤波器的要求,在微波滤波器的实际设计中具有很好的应用价值。-Microwave filters and integrated starting point is the choice of filter function, filtering function, the nature of the filter response. This paper presents a generalized Butterworth filter function, while retaining the advantages of their group delay at the same time, through the introduction of limited number of locations of transmission zeros, greatly improve the function of the band Butterworth characteristics, making it to adapt to modern communications microwave filter technology requirements, the actual design of microwave filters has a very good value.
