摘　　要：提出了一种带有陷波单元的新型高温超导滤波器设计结构,在输入、输出馈线附近设置陷波单元对特定频率产生陷波作用,在滤波器的传输特性上成传输零点,提高了滤波器设计的灵活性,基于这种新型结构设计了高边缘陡峭度滤波器和邻频双通带滤波器.This paper presents a new micro-strip HTS filter that include notch units coupled to the input and the output micro-strip lines of the filter. The notch units introduced the transmission zeros on the typical frequency response of the filter. Improvement in selectivity of the filter is evident. A practical design technology for this class of filters is introduced, three design examples of an eight-pole filter with one transmission zero on the skirt of the filter, a ten-pole filter with two transmission zeros on the skirt, and an eight-pole filter with transmission zero in pass-band are described.
