Exxelia to showcase advanced Microwave Capacitors and Ferrites at IMS Microwave week 2024

Exxelia is proud to announce its participation at IMS Microwave Week 2024 in Washington, D.C. from June 16 to 21, 2024. At booth 2108, Exxelia will highlight its main RF/Microwave capacitor ranges: Super HiQ & High-Power High-Q CP/CL series and also its innovative range of microwave ferrites, includ...

Exxelia will be showcasing their Super High-Q series of RF ceramic capacitors. These capacitors feature ultra-low ESR and can operate at voltages up to 1500V. They are available in sizes ranging from 0402 to 1210, offering capacitance values from 0.1pF to 1 000pF. They are ideal for advanced RF applications such as power amplifiers, mixers, filters and matching networks. 

High Q MLCC CP SeriesExxelia also features advanced High-Power High-Q series, designed for lower frequency applications with power handling up to 7200V and capacitance value up to 10nF. These capacitors are available in NPO and P90 dielectrics, offering exceptional performance with low ESR and ESL, making them ideal for the most demanding application. Those CP (P90) and CL (NP0) series are ideal for defense communication (VHF/UHF), medical MR body coils, and RF generators for plasma, semiconductor manufacturing, and extreme ultraviolet (EuV) lithography. 

 

Exxelia will also exhibit its comprehensive range of materials & tuning components, with a special focus on its cutting-edge microwave ferrite products. These advanced components are engineered to meet the rigorous demands of modern microwave applications, providing unparalleled performance and reliability. 

 

High Epsilon Ferrite YK21-DK21As a highlight of our presence at IMS Microwave Week, Exxelia will be pre-launching a new High-epsilon microwave ferrite. This new High-Epsilon Ferrite is featuring a permittivity of 21 and is available in two versions (YK21 and DK21) to address all power applications. It represents a significant advancement in ferrite technology, engineered to enhance the performance of high-frequency radar systems, especially in Active Electronically Scanned Array (AESA) radar applications. This new component delivers exceptional magnetic properties and stability, crucial for the optimal performance of isolator and circulator devices.

NEW INVAR TUNING ELEMENTS WITH SELF-LOCKING SYSTEM

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.

Exxelia Ohmcraft Custom Resistors Enable Metabolic Analyses of Live Cell Cultures in Pharmaceutical Research

To do so, they must rely on life science research and diagnostic instruments with complex high gain amplifier circuits. Leading manufacturers of this type of equipment have partnered with Exxelia Ohmcraft to design custom, high-resistance surface mount resistors that are essential to the function of these circuits. Specifically, oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) are two key indicators of mitochondrial respiration and glycolysis that provide a systems-level view of cellular metabolic function in cultured cells. The analyzer equipment conducts these measurements automatically. “The accuracy and reliability of these tools are crucial to the researchers’ ability to make progress in their studies, which have the potential to change—and save—lives,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “To meet the design needs of this particular application, we developed a custom resistor solution with a unique form factor and used special terminations to facilitate the manufacturability of the end product.” 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.
