Lignes de transmission imprimées pour les applications RF jusqu'à 67 GHz

Mohamed Moez Belhaj, Wei Wei, Emiliano Pallecchi, Colin Mismer, Isabelle Roch-Jeune, Henri Happy

Cette lettre présente la caractérisation radiofréquence (RF) des guides d'ondes coplanaires (CPW) imprimées avec et sans déformation. Le PET et le Kapton sont choisis comme substrats souples avec des températures de frittage différentes. Avec les paramètres d'impression à jet d'encre…

Mesure non linéaire dédiée aux amplificateurs de puissance radar excités par un train de pulses non périodique avec un NVNA basé sur des mélangeurs

Vincent Bridier, Damien Ducatteau, Hans-Joachim Simon, François Graux, Gilles Dambrine

Une mesure de forme d'onde temporelle en mode pulsé non périodique mais répétitif a été réalisée en utilisant un NVNA commercial basé sur des mélangeurs en mode périodique. Puis pour la première fois, un NVNA 20GHz six ports basé sur des mélangeurs a été modifié afin de mesurer trois…

Extra-low parasitic gate-to-contacts capacitance architecture for sub-14 nm transistor nodes

Heimanu Niebojewski, Cyrille Le Royer, Y. Morand, Olivier Rozeau, Marie-Anne Jaud, Emmanuel Dubois, Thierry Poiroux, D. Bensahel

We investigate in this work an original contact architecture to address 64 nm pitch transistor technology. This architecture, studied here in the fully-depleted silicon-on insulator (FDSOI) flavour, remains suitable for planar and 3D (trigate, FinFET) approaches. It includes a recessed gate-first…

Sub-THz characterisation of monolayer graphene

Ehsan Dadrasnia, Sujitha Puthukodan, Vinod V. K. Thalakkatukalathil, Horacio Lamela, Guillaume Ducournau, Jean-Francois Lampin, Frédéric Garet, Jean-Louis Coutaz

We explore the optical and electrical characteristics of monolayer graphene by using pulsed optoelectronic terahertz time-domain spectroscopy in the frequency range of 325-500 GHz based on fast direct measurements of phase and amplitude. We also show that these parameters can, however, be measured…

On-wafer differential noise figure measurement without couplers on a vector network analyzer

Yogadissen Andee, Alexandre Siligaris, Francois Graux, Francois Danneville

This papers presents a measurement technique for the noise figure of on-wafer differential amplifiers using 4-port network analyzers. The approach is based on the determination of the correlation of output noise waves in terms of the 4-port S-parameters and of the output noise powers. The…

Estimation of 60-GHz channels based on energy detection

Stephane Mebaley-Ekome, Laurent Clavier, Antoine Frappé, Eric Pierre Simon, Ilias Sourikopoulos

Estimation of time-varying channels is a common challenge for receiver architectures in wireless communications. Coherent receivers may require good knowledge of the channel impulse response for demodulation of the received symbols, after equalization of a dense multipath channel. However, very few…

Highly tunable Fabry-Perot resonators using piezoelectric phononic crystals

Bertrand Dubus, Marie -Fraise Ponge, Anne-Christine Hladky, Jerome O. Vasseur, Mai Phamthi

Theoretical and experimental analyses of piezoelectric stacks submitted to periodical electrical boundary conditions via electrodes, are conducted. These structures are shown to exhibit Bragg band gaps which are switched on or off by setting electrodes in short or open circuit. Band gap frequency…

Multi-carrier transmission of vectorial modulation schemes using electronic transceivers at 588 GHz

Guillaume Ducournau, P. Szriftgiser, D. Bacquet, Mohammed Zaknoune, Rédha Kassi, Jean-Francois Lampin

A reported is presented on the first communication system using vectorial modulation schemes above 500 GHz. Using Schottky-based electronic technologies at 588 GHz, potentialities of high-level multicarrier modulation schemes for wireless links are analysed. The wireless link is composed of an…

Guided waves in multilayered plates

Jiangong Yu, Jean-Etienne Lefebvre, Lahoucine Elmaimouni

Conventional orthogonal polynomial approach can solve the multilayered plate only when the material properties of two adjacent layers do not change significantly. This paper developed an improved orthogonal polynomial approach to solve wave propagation in multilayered plates with very dissimilar…
