Exxelia at EMV
Exxelia is pleased to exhibit at EMV 2019 in Stuttgart, Germany from March 19 to 21 inHall C2 Booth# 113, Exxelia will be introducing a new filter design conception.
Showcased at Exxelia’s booth #113 in Hall C2, will be Asymmetric filter solutions, the most optimized design in the market.
Smaller, lighter and consequently easier to install, Exxelia is the only manufacturer to solve HEMP requirements with Asymmetric filter designs, hence addressing the security challenges of tomorrow.
Exxelia pushes the limits of design with the new BDP series allowing a 50% space saving in your installation while keeping high technical specifications (insertion loss of 80dB, 1250A, 300kHz to 18GHz) and complying with the MIL STD 188 125 1&2 test requirements.
Asymmetric designs allow to combine safety and miniaturization while still handling HEMP and TEMPEST requirements. Three important benefits stand out from this conception, starting with a lower heat dissipation: as no magnetic field is generated, inductors suffer no heat dissipation. Secondly, the leakage is significantly lower thanks to a low value capacitance. Finally by using only one common inductor, these designs definitely save space.
Dr. Guillaume Aubard, Exxelia Filters’ Business Development Manager will be speaking at EMV Forum Hall C2-319 on March 20th from 3:40pm to 4pm about the Asymmetric filter solutions for HEMP and TEMPEST following by a Q&A.
WT83 - HIGH CAPACITANCE WET TANTALUM
Capacitance values have been strongly increased with Exxelia's new range of tantalum capacitors: WT83 is an extension of the ST79 families (according to CLR93 MIL values) but with double the capacitance. That is a pass for impactful miniaturization of existing designs by playing on both size and weight (for instance, WT83 offers 470µf 100V in a D size, whereas ST79 only gives 220µF in the same other conditions).
Innovative RF/Microwave components at IMS - Booth# 635 -
Ultra low ESR, high RF power and high self-resonant frequency The NHB series is a complete range of MLCC based on NPO dielectric material providing a very high Self Resonant Frequency and limiting the parasite Parallel Resonant Frequencies. The series is available in 1111 size with capacitance ranging from 0. 3pF to 100pF. NHB series offers excellent performance for RF power applications at high temperature up to 175°C and at 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of new NPO low loss rugged dielectrics. NHB series particularly fits for high power and high frequency applications such as: cellular base station equipment, broadband wireless service, point to point / multipoint radios and broadcasting equipment. Typical circuit applications: impedance matching, bypass, feedback, tuning, coupling and DC blocking. 100% invar tuning screws with self-locking system 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. High Q Factor Dielectric Resonators Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia 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), military radars.
