NEW INVAR TUNING ELEMENTS WITH SELF-LOCKING SYSTEM

Exxelia announces the release of new world-unique invar tuning elements featuring a self-locking system. The product has been designed to respond to increasing demand for high frequency tuning elements for space applications.


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.

50th anniversary of our Pessac manufacturing site

Our manufacturing site in Pessac is one of the 12 industrial sites of Exxelia. It has approximately 130 employees. “We produce essential but inexpensive parts, but we produce 50 million a year! And we have a year of visibility on our order books", "We produce parts in complex alloys here, but also our own recipes for insulating ceramics", assures Mickaël Pelé, Director of the Exxelia Pessac factory. This factory was founded in Pessac half a century ago: it is an integral part of the life of the City and the Region, which have actively participated in its development. Perfectly inserted into the local ecosystem, there are numerous interactions with neighboring institutions, laboratories, universities, schools and businesses. The Pessac factory was built in 1971 and inaugurated in September 1972. Its creation was initiated by Jean-Claude Asscher, President of the Tekelec-Airtronic group. Initially dedicated to distribution, the Tekelec-Airtronic group launched into manufacturing under license to then develop and industrialize its own products. Its development followed that of electronics, telecommunications and IT in France and around the world. The group will reach a significant size: in 1992, with 20 companies employing 3,000 people in different countries, its turnover will exceed one billion dollars. The Pessac plant remained associated with the group until the early 2000s.   Here is a retrospective of the event in video:

July 14: When our components take flight aboard iconic aircraft

The Rafale, flagship of French aviation The Rafale, a French multipurpose combat aircraft, is a symbol of air power. Exxelia is proud to be the preferred supplier of electronic components for this exceptional aircraft. Thanks to our expertise in high-performance components, the Rafale is able to deploy its maximum power during critical missions. Whether in the air or on the ground, Exxelia components guarantee the reliability and exceptional performance of the Rafale. Exxelia is onboard with Film & Tantalum capacitors, Ceramic capacitors, High voltage capacitor block, Electrolytic aluminum capacitors, Magnetic components, Slip Rings & potentiometers, Miniature filters & Resistors.     The Alpha Jet, ambassador of French excellence The Alpha Jet, an advanced training aircraft used by several air forces around the world, is another example of aircraft that carry Exxelia components. With its maneuverability and versatility, the Alpha Jet is a preferred choice for pilot training and reconnaissance missions. Exxelia contributes to the reliability of this aircraft by supplying state-of-the-art electronic components for aeronautics, thus guaranteeing its proper functioning and safety. Our miniature capacitors with a high capacitance value from the CNC series range equip the Aphajet https://exxelia.com/en/product/detail/2/cnc-series     The F-16, international cooperation When we talk about the national holiday of July 14, it is also important to highlight the international partnerships that strengthen our aeronautical industry. The F-16, a multipurpose combat aircraft developed in collaboration with the United States, is a striking example of this cooperation. Exxelia supplies essential components for the F-16, thus contributing to the success of this strategic alliance.     The Tiger Helicopter: Air Force in Action The Tiger helicopter embodies the power and versatility of combat helicopters. Whether for reconnaissance, fire support or anti-tank missions, the Tiger is a reference in terms of operational performance. Exxelia contributes to the reliability of this aircraft by supplying state-of-the-art electronic components for defense.     The A400M, a giant of the air The A400M multipurpose military transporter is another aircraft that proudly incorporates Exxelia components. Designed for tactical, strategic and logistical transport missions, the A400M is a major asset for air forces. We equip the engine control & monitoring unit (EPMU), but also the MTU Aeroengines with our PET PM 90R2 47uF 20% 200V polyester film capacitors and the ICM Interconnection module - Transient filter design with C Series C48K high voltage ceramic capacitors (C480YCW 10nF 10% 500V - C280YCW 100nF 10% 500V).                 Custom design film : optimized characteristics and integration  SPT1221W 300nF 10% 630V (SMD)  SP2983W 100uF 5% 500V               SP3012W 4,7uF 10% 500V (THT)
