Chalcogenide-Based Phase-Change Material RF Switches: Fundamentals, Design Considerations, and Circuit/System Applications

Chalcogenide-based PCM RF switches have undergone an impressive development since first being demonstrated in 2012. While initial demonstrations were aimed at exhibiting the record RF performance and massive RF system reconfiguration possibilities, more recent demonstrations have focused on developing and improving secondary metrics required for productization and mainstream commercial adoption. The technology is now positioned to become the first sub-10fs RON*COFF RF switch technology qualified in production high-volume manufacturing, placing an importance on understanding device fundamentals and how they translate to circuit implications. This presentation will discuss these topics as well as design considerations for PCM switch-based circuit and system applications.
