Microwaves and Optoelectronics Group - Microwaves

MOG-MW conducts research on RF, microwave and millimeter-wave circuits and systems for wireless, space and sensing applications. Its activities combine high-frequency circuit and system design, experimental characterization, and advanced modeling of devices, circuits and systems.

The group has long-standing expertise in power amplifiers and low-noise receivers for wireless transceivers. Research on power amplifiers focuses on high-efficiency multistage architectures in hybrid and MMIC technologies, based mainly on GaAs and GaN HEMT devices, with particular emphasis on load-modulated solutions such as Doherty power amplifiers. Applications range from the 2.4 GHz Wi-Fi band to X, K and Ka bands, using processes from major European and international foundries. The group also works on low-noise stages for CubeSat platforms, integrated analog/digital subsystems for SAR systems, stacked III-V modules, and cryogenic amplification architectures for quantum signals.

The MIMILAB laboratory supports design activities through linear and nonlinear high-frequency characterization, including load-pull measurements, system-level testing and linearization-oriented measurements. Modeling activities include the validation and development of linear, nonlinear, behavioral and neural-network-based models, together with optimization and order-reduction techniques. These activities are closely linked to PhD training and to the development of high-frequency hardware expertise for advanced wireless applications.
