Test method of frequency response based on diamond surface acoustic wave devices

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 Fab...

Description
Summary: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.
