EuMW 2017 - booth# 190

Exxelia is exhibiting at EuMW, in Nuremberg, Germany. From 10 to 12 October at booth# 190, the company will be showcasing high-rel microwave and RF components dedicated to a variety of demanding 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 @ 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of the NPO low loss rugged dielectrics. NHB series is particularly fit 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.

New entity, Exxelia Magnetics

This is an internal merger of two innovative, professional and complementary companies both designer and manufacturer of high-end would magnetic components, which have a history of successfully working together for a year. Exxelia Magnetics will have greater scale, breadth and capabilities to compete more effectively in the global marketplace. Exxelia Microspire Microspire was founded in 1978 and became part of Exxelia Group in 2008. Exxelia Microspire has been designing, developing and manufacturing wound components for over 35 years: transformers and inductors, electro-magnets, rotors and stators. Exxelia Microspire has several manufacturing sites, notably newly located low production cost facilities offering competitive solutions. Exxelia Microspire’s know-how includes standard winding technologies: linear (in RM, ETD, EP, EFD, ER, EQ and other formats) and toroid. For harsh environment applications with shock, vibration, and high temperature issues, Microspire offers innovative specific technologies including SESI, TT and CCM. Exxelia Microspire’s qualified technologies, clearly defined design rules and industrial organization provide the platform on which it is able to offer its customers optimal solutions. Exxelia N'Ergy Exxelia N’Ergy (ex N’Ergy) was acquired in 2015 by Exxelia Group.  Exxelia N’Ergy designs and manufactures passive specific electromagnetic components in small and medium range: Transformers, Chokes, Sensors (tachometer, gyros, …), Electromagnets.
