UWB Fastly–Tunable 0.5–50 GHz RF Transmitter Based on Integrated Photonics

“…N the last decade, the interest in software-defined ultrawideband (UWB) and tunable radio frequency (RF) apparatuses with low size, weight, and power consumption (SWaP), has grown dramatically, pushed by the new 6G vision where new human-centric services will be made possible by combinations of connected smart devices, mobile robots, and avatars [1]. In this vision, RF equipment shall enable a large number of fundamental applications as UWB communications [2], robot localization mapping and control [3]- [6] and high precision radars [7]- [9], all of them contributing in revolutionizing our life style through breakthroughs in communications (e.g., intuitive ubiquitous connectivity), in medicine (e.g., wearable devices and tele-medicine) , in security (e.g., pervasive situational awareness), in work processes (e.g., Industry 4.0), etc.. Tunable UWB apparatuses, This work was supported by the Italian Defense through the project DISTURB.…”

“…In the so-called Industry 4.0, precise location-aware applications also exploit low spectral density UWB signals for RF identification (RFID) [15]. Moreover, applications involving the use of robots have extended broadly, including services requiring the simultaneous operation of multiple robots, for which the precise localization & mapping and remote control can take advantage of rapidly tunable wideband RF connections [3]- [6]with bandwidth requirements in line with the 6G trends.…”

Tunable UWB apparatuses, i.e., systems with a very large fractional bandwidth and an absolute bandwidth > 500 GHz, also providing a wide frequency tunability, exhibit a low and tunable power spectral density that allow them being used as overlay signals in the same frequency range as existing legacy services without causing undue interferences [10], therefore bypassing the increasing issues of the overcrowded RF spectrum and the scarseness of available band.…”

“…In the so-called Industry 4.0, precise location-aware applications also exploit low spectral density UWB signals for RF identification (RFID) [15]. Moreover, applications involving the use of robots have extended broadly, including services requiring the simoultaneous operation of multiple robots, for which the precise localization & mapping and remote control can take advantage of rapidly tunable wideband RF connections [3]- [6] with bandwidth requirements in line with the 6G trends.…”
