Innovative RF/Microwave components at IMS - Booth# 635 -

Exxelia is exhibiting at IMS in Honolulu, USA. From June 04 to 06 at booth# 635. The company will be previewing several new microwave and RF components dedicated to a variety of industries including medical, transportation and defense.

Ultra low ESR, high RF power and high self-resonant frequency
The NHB series is a complete range of MLCC based on NPO dielectric material providing a very high Self Resonant Frequency and limiting the parasite Parallel Resonant Frequencies. The series is available in 1111 size with capacitance ranging from 0. 3pF to 100pF. NHB series offers excellent performance for RF power applications at high temperature up to 175°C and at 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of new NPO low loss rugged dielectrics. NHB series particularly fits for high power and high frequency applications such as: cellular base station equipment, broadband wireless service, point to point / multipoint radios and broadcasting equipment. Typical circuit applications: impedance matching, bypass, feedback, tuning, coupling and DC blocking.

100% invar tuning screws with self-locking system
Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed.

High Q Factor Dielectric Resonators
Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia has developed with support of ESA and CNES, a new high-end dielectric material, E7000 series, designed for high-end filters where high Q factor is requested.
E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q factor and the possibility to get all the temperature coefficients upon request. E7000 provides high-performance requested for space use in the frequency range 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Typical applications: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.

Nouveau Site Web

Le nouveau site internet offre une expérience utilisateur optimale grâce à un design intuitif, des fonctionnalités innovantes et des contenus adaptés aux différents types de produits : condensateurs, magnétiques, filtres, capteurs de position et slip rings.  Pour simplifier la sélection de produits, un moteur de recherche avec des filtres spécifiques à chaque technologie (capacitance, courant, température, fréquence, etc.) permet d’accéder en quelques clics à des produits ciblés et adaptés à ses besoins. Plus de 680 gammes sont répertoriées sur le site avec pour chacune la possibilité de télécharger une fiche technique, modèle 3D, photo HD, etc.   Les études techniques, guides d’application, livres blancs disponibles sous la rubrique « Ressources » donnent un aperçu détaillé de l’expertise d’Exxelia.   Enfin, une section « Application » présente les principaux marchés sur lesquels Exxelia opère aéronautique, spatial, défense, télécommunications, médical, et transports avec une sélection de produits adaptés à chaque sous-environnement : avionique & cockpit, actionneurs, satellites, radars, imagerie médicale, etc. Cette section contribue également à présenter la grande diversité de produits et de technologies proposés par le Groupe.  « Nous sommes fiers de notre nouveau site internet et de l’information pertinente qu’il fournit. Nous pensons qu’il améliorera l’expérience client et renforcera notre marque en tant que fournisseur leader de produits à haute fiabilité», Marie Evrard, Responsable Marketing et Communication d’Exxelia.   «Avec la croissance rapide de notre groupe, il nous semblait nécessaire d’offrir un site plus opérationnel tout en conservant un haut niveau de technicité. Plus fonctionnel, plus dynamique et plus graphique, ce site a pour objectif de rendre plus visible notre savoir-faire et favoriser les échanges avec nos clients », Jérôme Tabourel, Directeur Commercial et Marketing d’Exxelia. 

Composants magnétiques innovants à l’APEC 2017 – stand 623 –

Magnetic Components based on Adaptive CCM Technology Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint. Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204). The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC.  Component materials meet UL 94-V0 rating. Cost-effective Common-mode Chokes Qualified for Aerospace Exxelia designed this extensive and cost-effective range to be an easy commercial (COTS) solution for aerospace, defense, and other high-reliability applications. The TCM series is available in a through-hole package for horizontal or vertical mounting. TCM chokes are offered with inductances from 0.7 mH to 47 mH under rated currents from 0.3 to 4.0 A. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Excellent thermal properties allow the series to operate from -55° C to +125° C. The high mechanical performance of the component materials (all meeting to UL94 V0 rating) makes TCM a perfect fit for aviation, defense and transportation industries.
