Problems solved by technology

However, the existing test devices need to remove the online test equipment when performing calibration, and connect the corresponding calibration kits to the signal lines for calibration. One calibration will require multiple loading and unloading of the kits, which is not only inconvenient to operate, but also wastes human resources and work. time

Abstract

The invention belongs to the technical field of testing of surface acoustic wave devices, and discloses a surface acoustic wave device testing device and a testing method thereof. The surface acoustic wave device testing device includes a vector network analyzer and a BNC connecting assembly, and is characterized by also comprising a testing calibration device, wherein the BNC connecting assembly is used for connecting the vector network analyzer to the testing calibration device; according to the surface acoustic wave device testing device, the vector network analyzer is directly connected to the testing calibration device by the BNC connecting assembly, so that errors of device test results are reduced, and cost is saved; a calibration port is selected by a double-pole double-throw switch, so that selection of calibration types is achieved, the required calibration type can be selected through opening and closing the corresponding switch according to requirements, and the problems about inconvenient operation and low efficiency due to that the test suite needs to be assembled and disassembled for many times in each calibration in the prior art are overcome.

Description

technical field [0001] The invention belongs to the technical field of surface acoustic wave device testing, and in particular relates to a surface acoustic wave device testing device and a testing method thereof. Background technique [0002] Surface acoustic wave device technology is an emerging frontier subject combining acoustics, electronics, optics, piezoelectric materials and semiconductor planar technology. Surface acoustic wave devices are widely used in air traffic management, radar, sonar, electronic countermeasures, communications, environmental protection, etc. due to their advantages such as good stability, strong anti-electromagnetic interference, low power consumption, small size, and light texture. fields. The workload of the research, production and testing of surface acoustic wave devices has greatly increased with the wide range of applications, and problems have also followed. [0003] At present, the commonly used surface acoustic wave device testing ...
