| 摘 要： | 设计并制作了用于TD-SCDMA移动通信基站接收机前端的16阶高温超导窄带带通滤波器。该滤波器的中心频率为2017.5MHz,相对带宽为0.297%,由MgO衬底上的双面DyBa2Cu3O7超导薄膜加工而成。该滤波器77K温度下的实测带宽为5.83MHz,回波损耗好于15dB,边带陡峭度高达80dB/MHz;实测的中心频率等指标与仿真设计结果吻合很好。

| Abstract: | This paper reports a sixteen-pole high temperature superconducting(HTS) filter for applications in TD-SCDMA systems.The designed central frequency of the filter is 2017.5MHz and the fractional bandwidth is 0.297%.The filter was fabricated with double-coated DyBa2Cu3O7 film on MgO wafer.The measured performance at 77K shows that the bandwidth of the filter is 5.83MHz.The return loss is lower than 15dB.The slope is about 80dB/MHz,and further,the measured central frequency shows agreement with the simulated result. |
