A solid-mounted resonator-oscillator-based 4.596 GHz frequency synthesis

R. Boudot, Mingdong Li, V. Giordano, Nathalie Rolland, Paul-Alain Rolland, P. Vincent

This paper describes a 4.596 GHz frequency synthesis based on a 2.1 GHz solid mounted resonator (SMR) voltage-controlled oscillator (VCO). The SMR oscillator presents a chip size lower than 2 mm(2), a power consumption of 18.2 mW, and exhibits a phase noise of -89 dBc/Hz and -131 dBc/Hz at 2 kHz…

Indirect interband transition in hexagonal GaN

O Lancry, J.-L Farvacque, E Pichonat, Christophe Gaquière

In this paper, we report on optical investigations with Raman experiment to underline a new Ultra Violet (UV) luminescence band in hexagonal Gallium Nitride (GaN) at 4.56 eV. GaN is a direct band gap semiconductor, the photoluminescence peak corresponding to the energy gap at 3.43 eV dominates the…

Novel approach of UWB multi-band system based on orthogonal function for transports applications

F. Elbahhar, A. Lamari, Atika Rivenq, Jean-Michel Rouvaen, Marc Heddebaut, Tariq Boukour, Laila Sakkila

Ultra Wide Band (UWB) is based on the transmission of very short pulses with relatively low energy. This technology may see increased use in the wireless communications and sensing application. Having the available bandwidth of 7.5 GHz and the minimum signal bandwidth of 500 MHz, UWB systems can be…

Study of HF behaviour of railway power substation in reduced scale

H. Ouaddi, S. Baranowski, G. Nottet, B. Demoulin, L. Koné

The study presented in this paper is a first step of an EMC (Electromagnetic Compatibility) analysis of the behaviour of a railway power substation at high frequency. Before on site intensive experimentation, the approach is performed with a reduced scale model. The mock-up of the substation is…

Substrate integrated waveguide (SIW) inductive window band-pass filter based on post-wall irises

K. Nouri, Kamel Haddadi, O. Benzaïm, T. Lasri, M. Feham

In this article, we demonstrate a new inductive-window 5.245-GHz-band-pass filter based on post-wall irises by standard PcB process on Epoxy FR4 substrate. A new and easy to build microstrip-to-waveguide transition that consists of three tapers is also designed to connect the filter to standard…

Star-drops formed by periodic excitation and on an air cushion - A short review

Philippe Brunet, Jacco H Snoeijer

When simply put on a solid, a liquid drop usually adopts the shape of a spherical cap or a puddle depending on its volume and on the wetting conditions. However, when the drop is subjected to a periodic field, a parametric excitation can induce a transition of shape and can break the drop’s initial…
