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 Ohmcraft High Voltage Chip Dividers Enable Design Flexibility for Manufacturers of Semiconductor Equipment

 Exxelia Ohmcraft High Voltage Chip Dividers Enable Design Flexibility for Manufacturers of Semiconductor Equipment   ROCHESTER, N.Y., September 17, 2021—Microchips—also known as semiconductors—are critical to the function of everyday technologies like mobile phones, computers, radios, and televisions. To finetune the outputs of their main power supply, manufacturers of semiconductor production equipment have leveraged custom resistors from Exxelia Ohmcraft for more than 25 years for their high precision, high voltage and stability.   Exxelia Ohmcraft’s custom surface mount resistors and dividers offer semiconductor equipment engineers with maximum design flexibility in the smallest footprint, as they have the ability to specify both the resistance value of a surface mount divider and the divider ratio. This allows engineers to produce the necessary voltage and current required to create the highest-quality end products.   “Traditionally, high-voltage dividers are made using two different resistors, but our high voltage chip dividers integrate them into one part,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “We always work closely with our customers to ensure that we meet the specific design requirements necessary to create their quality technologies.”   Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.   # # #   About Exxelia Ohmcraft Exxelia Ohmcraft’s thick-film, surface mount resistors are engineered to meet application-specific needs. Our proprietary Micropen printing technology is the foundation for Exxelia Ohmcraft’s family of resistor products. Exxelia Ohmcraft’s precision leaded resistors are manufactured with our patented Micropen technology to create a unique serpentine design that withstands voltages up to 100kV and provides an unmatched level of performance and stability.
