In recent years, with the rapid growth of communication technology and the necessity for Radiofrequency (RF) front-end devices, the one-port Surface Acoustic Wave Resonator (SAWR) turns out to be a significant component in the design of a SAW device. Hence, the present study concentrates on and around one-port multi-layer SAW resonators with their applications in communication systems. A comparative and critical analysis of various parameters is explored including temperature coefficient of frequency (TCF), Quality factor (Q-factor), phase velocity, impedance ratio, bandwidth, sensitivity, metallization ratio, etc. to discuss the advantage and disadvantages of conventional one-port multi-layer SAW resonator. Through the analysis, future research trends as well as the applications of one port multi-layer SAW resonator are also discussed. The study also explores that the one port multi-layer SAW resonator finds employability in various applications like multimedia and mobile communication, medical field sensing technology, broadband signal processing at high frequencies, etc. Thus, significant, and efficient parameters of the resonator can be easily identified through comparative and critical analysis. The outcome of this study will help the researchers to enhance their work in this specific field in the future.

This paper proposes a wireless passive measurement system that supports real-time signal acquisition, multi-parameter crosstalk demodulation, and real-time storage and calculation. The system consists of a multi-parameter integrated sensor, an RF signal acquisition and demodulation circuit, and a multi-functional host computer software. The sensor signal acquisition circuit uses a wide frequency detection range (25 MHz–2.7 GHz) to meet the resonant frequency range of most sensors. Since the multi-parameter integrated sensors are affected by multiple factors, such as temperature and pressure, there will be interference between them, so the algorithm for multi-parameter decoupling is designed, and the software for sensor calibration and real-time demodulation is developed to improve the usability and flexibility of the measurement system. In the experiment, temperature and pressure dual-reference integrated surface acoustic wave sensors in the condition of 25–550 °C and 0–700 kPa are used for testing and verification. After experimental testing, the swept source of the signal acquisition circuit can meet the output accuracy in a wide frequency range, and the detection result of the sensor dynamic response is consistent with that of the network analyzer, with a maximum test error of 0.96%. Furthermore, the maximum temperature measurement error is 1.51%, and the maximum pressure measurement error is 5.136%. These results indicate that the proposed system has good detection accuracy and demodulation performance, and it can be used for multi-parameter wireless real-time detection and demodulation.
