Exxelia at IMS

Exxelia is pleased to exhibit at IMS in Philadelphia, USA. From June 11 to 15 at booth# 2050, the company will be previewing several high-reliability 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 in large batches

Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. 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 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication.

EXXELIA OHMCRAFT CUSTOM RESISTORS HELP ENSURE RELIABILITY OF MOST-DEPLOYED ANTI-TANK MISSILE IN THE WORLD

In times of warfare, the reliability of military weapons is absolutely critical to the success of a mission. For nearly a decade, military contractors have leveraged Exxelia Ohmcraft’s custom, high voltage resistors and dividers to ensure product performance in a variety of military applications, including the FGM-148 Javelin—the most-deployed anti-tank missile in the world. In a variety of military applications, including the FGM-148 Javelin—the most-deployed anti-tank missile in the world.“Missiles are exposed to extreme climate conditions and often sit idle—sometimes for several years—before they are launched. When that time comes, it is essential for those missiles to perform as expected,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “Exxelia Ohmcraft custom resistors are designed to support the rigorous precision and reliability specifications required by military suppliers to withstand the harsh environmental conditions, ensuring that the missile remains fully operational under all circumstances. Exxelia Ohmcraft performs a full range of military lot acceptance testing (LAT) on resistors as necessary, and works closely with military contractors to meet the design requirements for each particular application. In the case of the FGM-148 Javelin, a small, lightweight form factor was imperative to keep the missiles as lightweight and portable as possible. Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.

HLD EUROPE ENTERS INTO EXCLUSIVE NEGOTIATIONS WITH IK INVESTMENT PARTNERS TO ACQUIRE EXXELIA

Exxelia develops and manufactures complex passive components and electromechanical solutions for niche industrial markets such as aeronautics, space, defense, medical and rail, where product reliability and performance are essential. The group addresses main institutional players, systems and equipment manufacturers. Exxelia offers a complete and custom product range (capacitors, inductors, resistors, filters, position sensors and rotary joints) embedded into a large number of programs: from the Airbus A350 to the Boeing Dreamliner, from the Ariane 6 launcher to satellite constellations (such as Galileo, Oneweb, etc.), from the Rafale to the F-35, from subway coaches to high-speed trains, from MRI medical equipment to defibrillators. With an expected proforma revenue of around 170 million euros for 2019 and around 2,000 employees, Exxelia is present today in more than 30 countries and operates in Europe and the United States, in Morocco and in Vietnam through its production sites, its design centers as well as its network of sales partners. Avec l’appui de son nouvel actionnaire, Exxelia pourra intensifier sa démarche d’excellence opérationnelle et d’innovation et poursuivre sa stratégie d’internationalisation avec la pénétration de marchés porteurs tels que l’Inde ou la Chine et accélérer son développement aux Etats-Unis. With the support of its new shareholder, Exxelia will be able to intensify its operational excellence and innovation efforts, pursue its internationalization strategy with the penetration of high-growth markets such as India or China, and accelerate its development in the United States.
