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 acquires Deyoung MFG., INC.
“The DMI acquisition directly supports our Magnetics SBU expansion strategy. DMI’s strategic location in the Pacific Northwest aerospace market provides a key geographic location for driving growth and profitability,” said François Vignaud, Exxelia Magnetics’ SBU VP. “DMI is highly regarded for the quality of its products and the operational performance of its organization. DMI products can be found on most major commercial aerospace platforms, supporting in flight power, lighting and entertainment sub-systems.” “We welcome DMI into the Exxelia Group,” said Exxelia USA President Michael Thomas. “During its 40-plus years in business, DMI has built solid customer relationships with a strong brand reputation in the aerospace, medical and other high-reliability magnetics markets. Acquiring DMI creates the potential for both revenue and cost synergies related to cross selling and procurement savings as we leverage Exxelia Group’s broader global supply chain and operational excellence practices to support DMI’s operations.” According to Martin DeYoung, President & CEO of DMI, “We are excited to now be a part of Exxelia’s growth and expanded product offerings. The DeYoung’s recognized a shared business culture driven by a passion for quality and customer loyalty. By joining Exxelia Group we achieve a goal of meeting our strategic growth objectives while protecting our long standing relationships with our key aerospace customers and their contract manufacturers.” “This acquisition addresses our aerospace customers increasing requirements for global manufacturing access and timely support” stated Eric DeYoung, VP of Operations at DMI. “Together, we have global reach with the capability to serve our customers – whatever their size, location, or aerospace industry sector with one of the most comprehensive and competitive groups of design and manufacturing capabilities.”
Magnetic Components based on Adaptive CCM Technology at APEC – Booth# 653 –
Exxelia will exhibit the CCM series during the Applied Power Electronics Conference at Exxelia’s booth #623 from March 27-30, 2017 in Tampa, FL. Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint. Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204). The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Component materials meet UL 94-V0 rating. Exxelia can evaluate losses and related temperature rise thanks to an in-depth knowledge of CCM technology. Thermal resistance data is available for each package size. Exxelia can also manufacture products in CCM technology according to MIL-STD-981.
