Abstract

Radio frequency (RF) switches are pivotal components in modern wireless communication systems, playing a crucial role in 5 G, Internet of Things (IoT), and satellite communications. Non-volatile devices that offer zero static power consumption and miniaturization present a promising avenue for the fabrication of RF switches through resistive state switching using memristors. Nafion, a fluorosulphonated polytetrafluoroethylene copolymer, served as the dielectric in this study, enabling the preparation of Nafion-based non-volatile RF switches via a micro-nano process. The fabricated Nafion-based non-volatile RF switch exhibits a low insertion loss of 0.68 dB and an isolation of −11.55 dB at 43.5 GHz. It also has a nanosecond switching response time of 45 ns turn-on process, a critical performance metric for non-volatile RF devices. In addition, this device is switched by DC pulses, which significantly reduce the operational energy consumption of the RF switch. This advancement facilitates the development of reconfigurable wireless communication systems with high frequency.

一种高速响应的非易失性射频开关

射频（RF）开关是现代无线通信系统中的关键部件，在5g、物联网（IoT）和卫星通信中发挥着至关重要的作用。提供零静态功耗和小型化的非易失性器件为通过使用忆阻器的电阻状态开关制造射频开关提供了一条有前途的途径。Nafion是一种氟磺化聚四氟乙烯共聚物，在本研究中作为介质，通过微纳米工艺制备了基于Nafion的非挥发性射频开关。制备的基于nafon的非易失性射频开关在43.5 GHz时具有0.68 dB的低插入损耗和- 11.55 dB的隔离度。它还具有45 ns开启过程的纳秒级开关响应时间，这是非易失性RF器件的关键性能指标。此外，该器件采用直流脉冲开关，大大降低了射频开关的运行能耗。这一进步促进了高频可重构无线通信系统的发展。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
