Energy-efficient multi-functional and reconfigurable RF/microwave circuits

Next-generation RF/wireless applications will demand unprecedented capabilities in terms of DC-power-consumption reduction, RF frequency-agility, and multi-operability for their RF front-ends, for which there is not an adopted solution up to date. This research line investigates ground-breaking energy-efficient, ultra-reconfigurable, multi-functional, high-performance, smart RF/microwave subsystems and circuits as enabling hardware for these modern RF transceiver modules. Specifically, energy-efficient highly-flexible RF mono-/multi-band bandpass/bandstop filters and multiport schemes, advanced multi-functional RF/microwave circuits, frequency-agile multi-notch interference-mitigation devices, reflectionless RF passive components, novel low-loss RF-power-handling devices with electronic-tuning capability, original non-reciprocal RF passive circuits based on cutting-edge principles, and so forth are examples under this research line. In addition, the integration of these smart RF subsystems and circuits into advanced energy-efficient receiver and transmitter RF front-end chains are of interest. Significant advantages in terms of reduced size/volume, lower DC-power-consumption reduction, and enhanced multi-operability could result in a complete redefinition of future energy-efficient RF transceiver architectures. The research projects under this research line may have a large impact in many daily RF/wireless applications given the upcoming need for energy-efficient, high-versatile, multi-standard, multi-service, and multi-function RF/wireless transceivers. Among them, mobile communications (e.g., 5G), space scenarios (e.g., satellite communications, radio-navigation systems, or radio telescopes), Internet of Things (e.g., intelligent-wireless-sensor networks, RF tags, or applications for home), and radar (e.g., biomedical, structural-health monitoring, or automotive) are examples to be highlighted.
