Abstract
Early wireless pioneers relied on radio broadcasting to communicate. Our cell phones still use this 100-year-old idea. The next generation of 5G communication systems is expected to change this for the first time. Unlike broadcasting, 5G systems will rely on efficient point-to-point communication enabled by advanced millimeter-wave electronics and antenna arrays. Reconfigurable multiband microwave/mm-wave devices up to 100 GHz are envisioned for such systems. Their multifunctional characteristics tend to impose performance and cost requirements that cannot be met yet. In the first part of this talk I review our work on high-performance RF front-end components including tunable resonators, filters, limiters and switches. The emphasis will be on technology solutions based on tunable miniaturized cavities and cold-plasma electronics for sub-GHz to over 100-GHz bands. Furthermore, I will also discuss what the future may hold in terms of research and education in this field.
