Abstract：To test the surface acoustic wave (SAW) tag, the ADS semi-physical platform is proposed. This method utilizes the vector network analyzer for the measurement of the S parameters of the SAW tag, and establishes its abstract model in the ADS software. With the virtual excitation signal in the ADS, the echo signal of the tag is obtained by the ADS transient simulation function. The digital quadrature demodulation is implemented by the MATLAB software to measure the time delays and phases of the reflectors on the tag objectively and accurately. The SAW tag is tested by the above mentioned semi-physical platform, and the measurement results show the effectiveness of the ADS semi-physical platform.
