Rosenberger’s new EBC® (Efficient Board Connector) series is the ideal 5G board-to-board and board-to-module RF interconnect solution for active MIMO (Multiple Input Multiple Output) antennas and radios. Outstanding performance, low cost design and high mechanical stability make EBC® the perfect future-proof product for 5G radio interconnections.

For applications up to 8 GHz, EBC® connectors fulfill the challenging requirements caused by the exponential data volumes increases in future 5G networks. Essential characteristics include extremely small dimensions, radial and axial misalignments, different holding forces, minimum board-to-board distances, and fast and cost-effective assembly design. A key mechanical design feature is the locating side which is integrated in the bullet. One side has a smooth bore, while the other has a limited-detent design. The single PCB coupler provides a consistent footprint with preloaded outer contacts for ensuring contact optimization, the push/snap-on locking mechanism allows fast and easy disconnection.
