Power measurement setup development for on-wafer characterization at 185-191 GHz

Caroline Maye, Sylvie Lepilliet, Etienne Okada, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This article presents off-wafer scalar power setup dedicated to load-pull measurement for characterization of on-wafer active devices between 185 and 191 GHz. The system architecture allows us to determine the absorbed input power, the output power delivered to the load, the power added efficiency...

High-Frequency Noise Characterization and Modeling of Graphene Field-Effect Transistors

Marina Deng, Dalal Fadil, Wei Wei, Emiliano Pallecchi, Henri Happy, Gilles Dambrine, Magali de Matos, Thomas Zimmer, Sébastien Frégonèse

This article presents the small-signal and noise characterization of different technologies based on chemical vapor deposition (CVD) and silicon-carbide (SiC) graphene field-effect transistors (GFETs). The noise model, built on noise figure measurements under 50 Ω using the F 50 method, was...

Experimental Characterization of A Piezoelectric Transducer Array Taking into Account Crosstalk Phenomenon

Abdelmajid Bybi, Driss Khouili, Christian Granger, Mohammed Garoum, Ahmed Mzerd, Anne-Christine Hladky

Ultrasonic transducer arrays are generally composed of several piezoelectric elements arranged in 1D or 2D ways. Crosstalk is an undesirable phenomenon decreasing the performance of these devices. It generates parasitic displacements at the elements' radiating surfaces, which changes the...

Tunable frequency band structure in photo-responsive elastic metamaterials

A.S. S Gliozzi, M. Miniaci, A. Chiappone, A. Bergamini, F. Bosia, E. Descrovil, E Descrovi

An important issue in the field of elastic metamaterials is that their dynamic properties, such as the band gap frequencies, are typically fixed once the structure has been designed and fabricated. To overcome this limitation, many efforts have been made to conceive materials with adaptive elastic...
