【摘要】 高温超导移动电话基站子系统可以明显提高基站的性能 ,因此受到广泛的重视 .我们利用一个高性能超导滤波器 ,低噪声放大器 ,脉冲管制冷机和有关的微波线路集成了一台完整的高温超导移动通讯基站子系统原理性样机 .该子系统是针对DCS180 0基站系统 ,频段为1710～ 1785MHz,系统增益为 18dB ,该子系统是国内研制成功的首台原理性样机 .这表明对高温超导微波器件的应用研究已取得了阶段性的重要成果 .性能更好的实用子系统样机正在研制中更多还原

【Abstract】 A demonstration subsystem for mobile communications was developed. In this system, a high temperature superconducting microstrip bandpass filter on r-plane sapphire substrate was designed to have a quasi-elliptic function response, which was aimed to cover the whole receiver band of DCS 1800 base station. This filter was then integrated with a low noise amplifier and a pulse cryocooler, forming a demonstration subsystem.更多还原
