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),

What news do we have on Exxelia Film Capacitors ESA QPL ?

Exxelia Film Capacitors ESA QPL Parts already available on stock will be propose according the previsous version of the standard. Parts currently launched in production will be manufactured according the issue 2 of the specification.   This modification will affect only the new productions.   Perimeter Exxelia QPL film capacitors: PM90S, PM94S, PM907S, PM948S, HT86PS. Please find on the next slides the main updates of the 3rd issue of the ESCC 3006  standard (See document).       The Exxelia teams are at your disposal to answer your questions.

50th anniversary of our Pessac manufacturing site

Our manufacturing site in Pessac is one of the 12 industrial sites of Exxelia. It has approximately 130 employees. “We produce essential but inexpensive parts, but we produce 50 million a year! And we have a year of visibility on our order books", "We produce parts in complex alloys here, but also our own recipes for insulating ceramics", assures Mickaël Pelé, Director of the Exxelia Pessac factory. This factory was founded in Pessac half a century ago: it is an integral part of the life of the City and the Region, which have actively participated in its development. Perfectly inserted into the local ecosystem, there are numerous interactions with neighboring institutions, laboratories, universities, schools and businesses. The Pessac factory was built in 1971 and inaugurated in September 1972. Its creation was initiated by Jean-Claude Asscher, President of the Tekelec-Airtronic group. Initially dedicated to distribution, the Tekelec-Airtronic group launched into manufacturing under license to then develop and industrialize its own products. Its development followed that of electronics, telecommunications and IT in France and around the world. The group will reach a significant size: in 1992, with 20 companies employing 3,000 people in different countries, its turnover will exceed one billion dollars. The Pessac plant remained associated with the group until the early 2000s.   Here is a retrospective of the event in video:
