中文摘要：

为了减少噪音，当测试高频率设备时，在信号加了，一个单个港口的测试模式(S11 ) 被用来测试高频率(GHz ) 和在这的声学的波浪设备(SAWD ) 糊的双港口的表面的频率反应。测试的可行性被模仿 Fabry-Perot 模型证明。高周波的双港口的反响类型的钻石 SAWD 的频率反应被 S11 和双港口的测试模式(S21 ) 分别地测量。结果证明设备的优秀因素是 51.29， 3 dB 带宽是由 S11 模式测量的 27.8 MHz，它比 S21 模式好，并且与由模拟的频率反应曲线一致。

英文摘要：

In order to reduce the noises affixed to the signals when testing high frequency devices,a single-port test mode（S11） is used to test frequency response of high frequency（GHz） and dual-port surface acoustic wave devices（SAWDs） in this paper.The feasibility of the test is proved by simulating the Fabry-perot model.The frequency response of the high-frequency dual-port resonant-type diamond SAWD is measured by S11 and the dual-port test mode（S21）,respectively.The results show that the quality factor of the device is 51.29 and the 3 dB bandwidth is 27.8 MHz by S11-mode measurement,which is better than the S21 mode,and is consistent with the frequency response curve by simulation.
