摘　　要：采用φ３５ｍｍ的ＹＢＣＯ／ＬａＡｌＯ３薄膜制备出了微波延时５ｎｓ的超导微带延迟线。测量了延迟线的插损、延时和相位特性。在７７Ｋ，１ＧＨｚ、５ＧＨｚ、１０ＧＨｚ的插损分别为０．１４ｄｂ／ｎｓ、０．５５ｄｂ／ｕｓ、１．２ｄｂ／ｎｓ。描述了器件设计考虑，讨论了影响器件性能的主要因素。A superconducting microstrip delay line with delay time 5ns has been developed using YBCO/LaAlO3 thin film of 35mm - diameter. Its insertion and phase have been measured at 77K. The insertions at 1GHz, 5GHz and 10GHz are 0. 14db/ns, 0. 55db/ns and 1. 2db/ns respectively. The design is designed. The factors of influence on the performence are discussed.
