EDICON China

Exxelia is exhibiting at EDICON China, Shanghai. From April 25 to 27 at booth#122, 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 new 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 ScrewsEnsemble SIC SAFCO 1Invar-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
E7000 photoDielectric 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.

Microwave Ferrites, Coaxial & Dielectric Resonators : Ask now !

Exxelia offers a wide range, including: Coaxial resonators : Resonators generally used in filters, duplexers, DRO's, and VCO's over a wide frequency range: 300 MHz to 6 GHz. They are available in several dimensions: 2x2, 4x4, 6x6, and up to 12x12 mm, offering the best compromise between impedance, Q factor, and resonance frequency.     Dielectric resonators : The dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia, with the support of the ESA and CNES, has developed the E7000 series which offers narrow bandwidth with reduced size. The E7000 dielectric resonator is based on Ba-Mg-Ta materials which combine ultra-high quality factor and the possibility to obtain all temperature coefficients on request. E7000 presents the high performances required for space use in the frequency range of 5 to 32 GHz and ensures up to Qxf > 250,000 at 10 GHz. As one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Encouraged by the success of this new range, Exxelia is now able to supply larger batches (up to 20 kg of powder) while retaining the same product properties.   Ferrites : Ferrites are magnetic materials used in a variety of applications. They are particularly effective in suppressing electromagnetic interference and noise in high-frequency applications, making them indispensable for modern communication systems. Ferrites are offered in disc, triangle, or specific designs. These materials are based on Exxelia formulations, offering low deltaH (ΔH) conducive to reducing IMD. Their combination with a dielectric material allows for a wide choice of composites (FDA) to miniaturize isolator/circulator designs. Exxelia's ferrites are distinguished by their exceptional quality and superior performance. These ferrites are made from high-quality materials and benefit from state-of-the-art design and manufacturing processes. They have been tested for use in demanding environments and have demonstrated exceptional reliability in applications up to 40 GHz.
