Nouvelle gamme de vis hyperfréquence autofreinées en Invar

Exxelia introduit une nouvelle gamme de vis hyperfréquence autofréinées en invar. Cette gamme a été spécialement conçue pour répondre aux exigences des applications spatiales.

 

Working frequencies in Space applications are shifting to Ka, Ku or even Q band, while cavity filters are undergoing the general trend towards miniaturization: this context calls for a much more precise and stable tuning element now offered by Exxelia Temex, daughter company of Exxelia, through their last innovative and unrivalled solution to incorporate a self-locking system into their Invar Tuning Elements.

Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed.

Boost your project with Exxelia film capacitors with reduced delivery times!

We are pleased to announce that certain products in our RA and KM film capacitor series, as well as our special PMR range (for the medical and railway markets), now benefit from reduced delivery times.   Reduced lead times for film capacitors of the RA (Polypropylene PP) and KM (Polyphenylene sulfide PPS) families: Indeed, delivery times for film capacitors in the RA and KM ranges have been considerably reduced. Previously, these products had an average lead time of 20 weeks, but through efforts to optimize our supply chain, we have managed to reduce this lead time to just 8 weeks on average! One of the key product of this range is the KM 111 S/T. This high performance film capacitor is ideal for a wide range of applications, such as power electronics, filters, inverters. The KM 111 S/T provides the precise capacitance value needed for special aviation electromechanical applications. With its high operating voltage and high energy density, the KM 111 S/T offers outstanding performance. And now, with a lead time reduced to just 8 weeks, you can incorporate it into your designs faster, accelerating your product development. Products KM 111 KM 21 KM 311 KM 50 KM 501 KM 531 KM 601 KM 62 KM 7 T KM 7 C KM 711 KM 78 KM 78R KM 82 KM 82 RS KM 90 KM 90P KM 94 KM 97 KM 31 KM 511 KM 531 KM 90T KM 90P Products RA 01 RA 02 RA 03 RA 04 RA 11 RA 12 RA 13 RA 14 RA 21 RA 22 RA 23 RA 24 RA 31 RA 32 RA 33 RA 34 RA 75   A revolution in delivery times with the film capacitors of the PMR (Polyphenylene Sulfide PPS) family: Our special PMR range, designed for medical and railway applications, also saw a significant improvement in its delivery times. In some cases, we have been able to reduce the usual delivery times for these specific products by a factor of 10. This means you can now get the PMR range film capacitors you need in record time! Film capacitors in the PMR range are specifically designed to meet the stringent requirements of medical and railway applications. Their reliability, stability, and extended life make them ideal choices for medical equipment, monitoring devices, rail transportation systems, and more. Thanks to our reduced delivery times, you can now benefit from these advantages without waiting long to receive your products.   PMR EFCO PMR 4 PMR 64

Microwave Ferrites, Coaxial & Dielectric Resonators : Ask now !

Exxelia offers a wide range, including: Coaxial resonators : Resonators generally used in filters, duplexers, DRO's, and VCO's over a wide frequency range: 300 MHz to 6 GHz. They are available in several dimensions: 2x2, 4x4, 6x6, and up to 12x12 mm, offering the best compromise between impedance, Q factor, and resonance frequency.     Dielectric resonators : The dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia, with the support of the ESA and CNES, has developed the E7000 series which offers narrow bandwidth with reduced size. The E7000 dielectric resonator is based on Ba-Mg-Ta materials which combine ultra-high quality factor and the possibility to obtain all temperature coefficients on request. E7000 presents the high performances required for space use in the frequency range of 5 to 32 GHz and ensures up to Qxf > 250,000 at 10 GHz. As one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Encouraged by the success of this new range, Exxelia is now able to supply larger batches (up to 20 kg of powder) while retaining the same product properties.   Ferrites : Ferrites are magnetic materials used in a variety of applications. They are particularly effective in suppressing electromagnetic interference and noise in high-frequency applications, making them indispensable for modern communication systems. Ferrites are offered in disc, triangle, or specific designs. These materials are based on Exxelia formulations, offering low deltaH (ΔH) conducive to reducing IMD. Their combination with a dielectric material allows for a wide choice of composites (FDA) to miniaturize isolator/circulator designs. Exxelia's ferrites are distinguished by their exceptional quality and superior performance. These ferrites are made from high-quality materials and benefit from state-of-the-art design and manufacturing processes. They have been tested for use in demanding environments and have demonstrated exceptional reliability in applications up to 40 GHz. Contact us to help you choose the ferrites that best suit your needs.
