The next generation of 5G communication systems comes with vastly different requirements for the RF front-ends from what our existing systems are used to. Reconfigurable RF devices in new bands up to 100 GHz are envisioned for 5G systems. Additionally, their multifunctional characteristics tend to impose linearity requirements and interference mitigation schemes that cannot be met today even in existing bands. It becomes imperative to develop new technologies and architectures that will help us meet these goals. This seminar will focus on RF front-end resonators and filters that often present the most difficult challenges in such designs. This presentation will review a new technology of miniaturized broadly-reconfigurable cavity resonators that simultaneously exhibit wide tuning range (> one octave) and high quality factors (~1,000) in a mobile form factor up to W band frequencies. It will also present novel multi-band solutions that exhibit i) independent control of frequency and bandwidth, ii) transmission zero creation for all reconfigurable states, iii) intrinsic switching-off capability for transmission bands, and iv) ease of extrapolation to an arbitrary number of passbands. Future needs, unmet challenges, and possible approaches will conclude this presentation.
