Exxelia, a global designer and manufacturer of complex passive components and high-precision sub-systems, has announced that it will take part as an exhibitor at the upcoming IMS 2017 event to be held in Honolulu, Hawaii from 4 to 6 June, 2017. The company will be previewing several new microwave and RF components dedicated to a variety of industries including medical, transportation and defense.
Exxelia will be showcasing all of the new RF and microwave products at their event booth (Booth #635) which will also include three of its latest offerings:
Ultra Low ESR, High RF Power and High Self-Resonant Frequency MLCC's
The new NHB series which 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 MLCC's are available in a 1111 size with capacitance ranging from 0.3 pF to 100 pF. The series offers excellent performance for RF power applications at high temperatures up to 175°C and at 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and the new NPO low loss rugged dielectrics. The NHB series are ideal 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 which is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought after for its very low coefficient of thermal expansion. With 1.1 ppm and 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 for making tuning elements. With the working temperature range in space being so wide, this property becomes essential for reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on tuning elements 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 with the support of ESA and CNES has developed a new high-end dielectric material, the E7000 series, designed for high-end filters where a high Q factor is required. The E7000 is based on Ba-Mg-Ta materials that combine an ultra-high Q factor with the possibility to get a wide range of temperature coefficients (upon request). It provides the high-performance required for use in space at frequencies from 5 to 32 GHz, and guarantees a Qxf > 250,000 at 10 GHz. The applications for these dielectric radars include Satellite multiplexing filter devices, radio links for communication systems (LMDS), and military radars.
