空带高温超导滤波器的研制

摘要

The design of S - band narrow - band HTS filter was introduced. Based on simulation modeling and topology optimization technology, HTS filter was successfully fabricated with the center frequency 2. lGHz, bandwidth 6MHz, group delay 18. 321ns at 71.7% bandwidth , insertion loss 0.5dB, band gradient 17dB/MHz, and VSWR is better than 1.5. This filter needn' t to tune, which is benefit to engineering application.%介绍了S波段窄带高温超导滤波器的设计过程,采用仿真建模和拓扑结构优化关键技术,在不需调谐的情况下,研制成功中心频率2.1GHz,带宽6MHz,群延时起伏在4.3MHz(71.7％带宽)内达到了18.32Ins,插入损耗小于0.5dB,带边陡度大于17dB/MHz,驻波比优于1.5的高温超导滤波器,有利于器件的工程化应用.
