摘要
针对低频率高温超导滤波器设计时尺寸大的问题,设计了一种对称双螺旋的微带谐振器,结构紧凑,可有效减小谐振器尺寸,且性能稳定,采用本谐振器结构设计了一种低频率的高温超导滤波器,滤波器中心频率为455.25MHz,相对带宽为1.05%,得到了较理想的设计结果。
This paper presented a compact symmetrical dual-spiral micro-strip resonators suited for low frequency HTS filter. The resonator significantly reduced size compared with zigzag meander line resonator. A miniaturized ten-pole low frequency HTS band-pass filter was designed, whose central frequency was 455.25 MHz and fractional bandwidth was 1.05%.
