Abstract:

The Next Generation of Wireless (6G) is expected to revolutionize wireless connectivity, offering 10-100x higher data rates, lower latency and multi-standard operability. However, the deployment of 6G systems comes across critical challenges, particularly in mitigating interference, accessing the over congested RF spectrum and in ensuring power efficiency. To address these challenges, disruptive RF technology developments are required for the RF filters of their RF front-end aiming for higher transfer function versatility, ultra-wide tuning range and higher operational frequencies whilst occupying the smallest possible footprint. This webinar will provide a comprehensive overview of new types of highly-versatile, multi-functional and highly-miniaturized RF filters. We’ll discuss new design techniques, tuning concepts and practical realization approaches that lead to multiple levels of tunability (i.e, center frequency, bandwidth, transfer function type), multi-octave tuning range and multi-functionality. The seminar will present various integration concepts for 3D high-Q and tunable cavity-based RF filters for frequencies as low as 100 MHz to as high as 100 GHz. Multi-octave tuning concepts using new tuning methods and integration schemes focused on manifolds and new materials will be discussed. Furthermore, we will discuss holistic RF front-end design methods centered around RF co-designed filters aiming for miniaturization and improved RF performance. New design concepts that facilitate the realization of multi-functional RF components with a specific emphasis of RF filters with co-embedded isolator/circulator and amplifier functionality will be presented as key RF technology elements for full-duplex and joined communication and sensing (JCAS) systems. Lastly, we will discuss recent advancements in the realization of highly-functional RF filters incorporating  large number of RF functions within the volume of a single RF filtering component.
