EXXELIA, A EUROPEAN SOURCE OF HIGH Q FACTOR DIELECTRIC RESONATORS

Exxelia presents its new dielectric resonator, the E7000 series. The series has been designed for high-end filters where Q factor is critical, especially in space or military applications.


Operating frequencies in wireless communications have shifted towards high frequency band and thus frequencies higher than 1 Ghz are now commonly utilized. In addition, the microwave frequency spectrum becoming severely crowded and sub-divided into many different frequency bands, designers are systematically looking for resonators giving them a narrow bandwidth with smaller size.

Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia Temex, daughter company of Exxelia Group, 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),

Exxelia at SIAE 2023 (Paris Air Show)

As an expert in high reliability products in a wide range of fields, Exxelia will be exhibiting its products this year.   On its "Embedded Products" cluster, bringing together components that can be mounted on a satellite or aircraft, Exxelia will be presenting two innovations that are particularly well suited to the challenges of the aviation of the future and the objectives of decarbonisation of the air. Its latest film capacitor innovation called MML™ (named after its "Miniature Micro-Layer" dielectric) shows an energy density up to 4 times higher than other film dielectrics. MML® technology makes power capacitors smaller, lighter and compatible with higher temperatures, and is therefore particularly suitable for DC-Link, decoupling & charge-discharge applications.   Alongside MML™ components, Exxelia will also be exhibiting the latest innovations in magnetic components, saving up to 40% in weight and 20% in volume while dissipating more power, some of which have been designed for eVTOL applications, as well as the CCM & Dual Active Bridge multi-output transformers.   Come and discover the latest innovations from Exxelia at our booth during the event. We have a range of high-quality products (Capacitors, Filters, Magnetics, Materials & Tuning Components, Position Sensors, Ohmcraft Resistors, Slip Rings & Rotary Joints) designed to meet the needs of your industry. We can't wait to show you how our solutions can improve your projects and increase your efficiency.   Don't miss the opportunity to meet our team of experts and find out how we can help you achieve your goals. Join us at our booth for an enlightening experience.
