【摘要】 研制了一种基于CDMA移动通信系统接收频段的高温超导滤波器,滤波器的电路芯片采用蒸镀于2英寸0.5mmMgO基片上的双面DyBa2Cu3O7高温超导薄膜,设计制作的滤波器中心频率为830MHz,通带宽度为10MHz,最终滤波器的工作温度为70K,各项技术指标均满足了CDMA系统的要求.更多还原

【Abstract】 This paper designed a HTS filter for CDMA mobile communication system. The filter was designed and fabricated using double-sided DyBa₂Cu₃O₇ thin films on 2-inch diameter and 0.5mm thickness MgO wafer. The center frequency of the filter is 830MHz, the band-width is 10MHz, At the work temperature 70K, all the specs suit for the communication system.更多还原
