Larger Batches of High Q-Factor Dielectric Resonators

Exxelia can now produce larger batches of its E7000 series for increased cost-effectiveness. Designed for high-end filters where Q-factor is critical, especially in space or military applications, the E7000 series of dielectric resonator features tremendous properties.

Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. 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 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ.

Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication.

Typical applications for the E7000 series: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.

Exxelia at Eurosatory

State-of-the art absolute optical encoders Exxelia has acquired deep expertise in the development of contactless position sensors of several type: absolute and incremental optical encoders, magnetic technology and inductive sensors. Several ranges of state-of-the-art absolute optical encoders will be showcased at the company booth - Hall 5A booth# E543. Absolute optical encoders are position sensors that use optical signals to identify an absolute angular position. They provide the highest resolution, operating speed reliability as well as long life operation in most demanding environments. Exxelia ranges of absolute optical encoders offer very high performance levels for a very small footprint: high precision (<30arcsc.), high resolution (up to 21 bits), extreme thinness (10mm) and EMI EMC compatibility. With their compact design, Exxelia miniature encoders meet the requirements of the most demanding application such as aerospace, defense, medical, oil & mining industries. Various protocols are available to match with any application.  Exxelia encoders can be easily combined with other functions such as slip rings to provide customers turkey solutions.   Two new ranges of MIL-qualified wet tantalum capacitors: MIL39006/22 & MIL39006/25 The recently introduced ranges of MIL-qualified tantalum capacitors will be showcased on the company booth. MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types featuring hermetically sealed cylindrical tantalum cases and axial leads are available in T1, T2 T3 and T4 cases with extended capacitance and voltage ratings. MIL 39006/22 is qualified for voltages from 6V to 125V and provides from 1200µF @6V to 56µF @125V. MIL 39006/25 is qualified for voltages from 25V to 125V and delivers from 680µF @25V to 82µF @125V. Both ranges combine high energy density with a large operating temperature range of -55°C - +125°C and H vibrations and shocks resistance.
