介绍了利用在３６°Ｙ－ＸＬｉＴａＯ３、６４°Ｙ－Ｘ ＬｉＮｂＯ３、４１°Ｙ－Ｘ ＬｉＮｂＯ３基片漏声表面波设计制作的宽带低损耗滤波器，给出了用耦合模理论模拟的曲线和实验结果，其相对带宽为２ ．８％～６． ５％，插损为１．７～２．４ ｄＢ，带外抑制大于４５ ｄＢ。
A broadband low loss filter based on the surface acoustic wave (SAW) design of 36 ° Y-XLiTaO3, 64 ° Y-X LiNbO3, 41 ° Y-X LiNbO3 substrate is introduced. The curves and experiments As a result, its relative bandwidth is two. 8% ~ 6. 5% insertion loss 1.7 ~ 2.4 dB, out of band suppression greater than 45 dB.
