Specific criteria have been applied to ensure that the RF contacts can be integrated into each of SOURIAU's 16 designs for 38999, with standardized 8-gauge sockets. Their advanced design and careful control of mechanical tolerances allow users to ensure high-quality RF transmission, even under the adverse conditions specified in the MIL standard (vibration, shocks, salt spray, etc.).The new BMA RF coaxial contacts stand out for their high performance. Each contact has its own shielding ring that complements the D38999 shielding ring. This provides doubly protected RF transmission against EMI. Furthermore, the excellent waveform stability achieved by the BMA coaxial interface allows users to avoid breaks in coaxial lines.
This means that the long coaxial cables currently used in some aircraft can be segmented while maintaining satisfactory link performance. This type of segmentation facilitates modular construction and maintenance by aerospace integrators.
Finally, SOURIAU also manufactures 38999 connectors with composite materials to meet weight limitations, as well as RoHS shields that offer an alternative to cadmium (zinc-nickel, QPL protection code Z) to meet the latest RoHS requirements.
BMA RF coaxial contacts thus provide efficient solutions for RF transmission in a certified D38999 environment. This allows SOURIAU to offer its RoHS-compliant protection with composite material and zinc-nickel technologies in MIL environments, in accordance with proven high-frequency coaxial communication technology.
