0.2-<i>μ</i>m InP/GaAsSb DHBT Transferred on Si-HR With 28 mW/<i>μ</i>m² at 94 GHz

Abdelmalek Zemour, Malek Zegaoui, Christophe Coinon, Yannick Roelens, Etienne Okada, Pascal Chevalier, Mohammed Zaknoune

We present 94 GHz large-signal load-pull measurements of a transferred InP/GaAsSb double heterojunction bipolar transistor fabricated on a high-resistivity silicon (Si-HR) substrate. The characterized device features an emitter area of 0.19 × 8.9 µm 2 . Biased for highest power, an output power of...

Characterization of Closely‐Located Users in Measured Cell‐Free Massive MIMO Networks

Dimitrios Georgios Nixarlidis, Eric Pierre Simon, Davy Gaillot, Valentin Picquet, Pierre Laly, Joumana Farah

<div><p>This letter investigates the spatial separability of closely-located users in cell-free massive multiple-input multiple-output (CF-mMIMO) systems using high-diversity real-world channel measurements. We evaluate the orthogonality of four closely-located users under various CF...

Steerable Thin-Film Electrode Array for Cochlear Implantation: Design and Development for Future Atraumatic Insertion

Ahmad Itawi, Bacem Zribi, Prabhakar Sidambaram, Thanh Hang Tran, Guillaume Tourrel, Renato Torres, Sofiane Ghenna, Sébastien Grondel, Yann Nguyen, Cedric Plesse, Eric Cattan

During cochlear implant surgery, standard electrode arrays are inserted into the scala tympani to stimulate the spiral ganglion cells and rehabilitate hearing in deaf patients. However, conventional electrode arrays' stiffness and passive nature lead to potential trauma or incomplete insertion...

Inkjet-Printing with Micrometer Resolution on Paper for Flexible RF Applications

Fawzi Bouakkaz, Riccardo Sargeni, Sylvie Lepilliet, Simon Skrzypczak, Emiliano Pallecchi, Gianluca Fiori, Henri Happy

Geometry is a critical factor in radio frequency design that directly affects the performance and efficiency of RF components and systems. The characteristic impedance and the propagation constant of transmission lines are affected by the conductor width, spacing, and the dielectric properties. In...

Low-loss, 1-m long length, silica based hollow-core THz waveguide operating at 1 THz

Georges Humbert, Jean-Louis Auguste, Guillaume Ducournau, Jean-Francois Lampin

A hollow-core THz waveguide composed of silica capillaries is proposed for low-loss THz wave propagation. Silica, despite its large absorption coefficient at THz frequencies, offers numerous fabrication advantages for developing THz waveguides. A numerical study on the anti-resonant guiding...
