| Abstract(in English) | YBa_2Cu_3O_y(YBCO)/CeO_2 thin films were deposited on r-, c-, and a-plane sapphire substrates(r-, c-, a-AI_2O_3). The YBCO films on the a-AI_2O_3 showed c-axis orientation and a critical temperature T_c of 88.6 K which is nearly the same as that on the r-AI_2O_3. Etching characteristics of the YBCO thin films by an ECR etching system were investigated. The etching rate on the area of 20 mm in diameter was approximately uniform, and its difference of the rate was below 4.3 %. Duplexer was designed using 3- and 5-pole Chebychev-type band pass filter (BPF). Sharper skirt characteristic and better duplexer distribute-function could be got as increased the pole of Chebychev-type BPF, through simulations. |
