摘要

我们提出的设计，制造和实验测试的带宽可重构表面声波（SAW）滤波器集成二氧化钒（VO2）为基础的射频（RF）开关。我们提出了一种利用VO2的相变特性的设计，它在绝缘和导电状态之间转换，从而实现SAW滤波器带宽的动态重新配置。通过修改数字间换能器（IDT）配置，可以改变谐振器的机电耦合系数（k2），从而实现跨不同带宽的重新配置。实验结果证明了所提出的设计提供的带宽可调性，并且制作的原型滤波器表明，单片集成的基于vo2的RF开关可以为可重构的声学滤波器提供灵活的解决方案。据我们所知，这项工作代表了带宽可重构声学滤波器的首次演示，该滤波器带有带声学谐振器的单片集成RF开关。

PCM-Based Bandwidth-Reconfigurable Acoustic-Wave Filter

We present the design, fabrication, and experimental testing of bandwidth-reconfigurable surface acoustic-wave (SAW) filters with integrated vanadium dioxide (VO2)-based radio frequency (RF) switches. We propose a design that utilizes the phase-change properties of VO2, which transitions between insulating and conductive states to enable dynamic reconfiguration of the SAW filter bandwidth. By modifying the interdigital transducer (IDT) configurations, the electromechanical coupling coefficient (k2) of the resonators can be varied, thus enabling the reconfiguration across different bandwidths. Experimental results demonstrated the bandwidth adjustability offered by the proposed design, and the fabricated prototype filters suggested that monolithically integrated VO2-based RF switches can provide a flexible solution for reconfigurable acoustic filters. To the best of our knowledge, this work represents the first demonstration of bandwidth-reconfigurable acoustic filters with monolithically integrated RF switches with acoustic resonators.

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
