MEMS Acoustic Wave Devices Hetero Acoustic Layer High frequency
◎研究内容
The acoustic wave devices are crucial in RF front-ends for its precise filtering, compact size, and cost-effectiveness, ensuring efficient signal transmission in wireless systems. Now, more than hundreds of acoustic wave filters are used in smart phones. Due to the crowded frequency bands and increased demands for data transfer rate, there are several new requirements for acoustic wave devices. For example, the steep passband, spurious free and good temperature characteristics are required in frequency bands below 3.4 GHz. High performance acoustic filters with large bandwidth (BW) are required at the frequency ranges over 5 GHz. Based on the above requirements, my interests are to develop novel surface acoustic wave (SAW) and bulk acoustic wave (BAW) devices for the next generation wireless communications and other applications. These researches ensure clear, interference-free data exchange between devices. This enables reliable, real-time communication essential for IoT and interconnected systems.
