PCB Connectors
Solutions for Board-to-Board and Board-to-Cable Connections
Rosenberger provides a wide range of RF coaxial connectors for PCB applications. A wide range of installation variants are available. The range incorporates new innovative series, e.g. EBC®, SMP Infinty und VIA®, as well as common series such as SMP, Mini-SMP, Longwipe-SMP, P-SMP, FMC and Micro-RF. Rosenberger also offers optimum PCB connectors for many common standard RF series such as SMA, QMA, SMB, MCX and Mini-Coax as well as for automotive or test and measurement technology applications.

In addition to small board-to-board distances, essential characteristics are equalization of radial and axial misalignments, the different holding forces and a fast and cost-effective assembly design. The surface-mount technology facilitates very good transmission characteristics and automatic installation using the special tape & reel packaging.
Rosenberger EBC®
Rosenberger’s new EBC® series is the ideal 5G board-to-board and board-to-module RF interconnect solution for sub 6 GHz massive MIMO active antennas and radios. Its outstanding performance and rigorous design to cost make this solution the ideal choice for 5G radio interconnections.
Rosenberger EBC®
  • Preloaded outer contacts for contact optimization
  • One design for many applications
  • Self-centering / self-alignment – blind mateability
  • Optimized for PCB and filters
  • Simple filter connection
  • Excellent signal integrity (SI)
  • Excellent shielding required for MIMO applications (EMI)
  • Designed for mass-volume production
  • 100% design to cost; lowest TCO on the market
  • Only one PCB coupler design – consistent footprint
  • Detent type on the bullet (limited detent – smooth bore)
  • Small outline
  • Best-in-class axial and radial compensation
VIA® – Variable Interface Adaptor
Rosenberger has incorporated all of the benefits of the different board-to-board and board-to-module HF connections (SMP, LW-SMP, P-SMP, and MBX) into the newly developed VIA® (Variable Interface Adaptor) B2B series. The mechanical design features one key USP to win over prospective customers: the locating side is integrated in the adaptor (bullet). One side of the bullet has a smooth bore, while the other side has a limited-detent design.

PRIZM® Light Turn® - High-Speed Fiber Optic Transmission - directly at the PCB
No more limitations from PCB copper strip lines

Constantly increasing bandwidth requirements in all areas of communication and computing are putting greater demands on networking I/O equipment. Current edge-mount copper or fiber interfaces are at their limits. Embedded parallel-optics have become the solution of choice to meet these demands. High-performance routers, switches and computers have already utilized this technology for a decade.

PRIZM® Light Turn®
Rosenberger: First manufacturer of MTP® cabling systems in Europe guarantees highest level of availability, outstanding product and service quality.

Embedded opto-electrical modules, optical engines, utilize parallel-optics transmitter and receiver arrays. For optimum signal integrity, thermal management, I/O consolidation and EMI/ESD, the opto-electrical modules are directly mounted close to the processors at the PCB. Parallel-optic links can complement electronic signaling in parallel lanes like XAUI und PCIe.

Parallel optics applications:
  • links between nodes of super-computers
  • switches in international internet gateways
  • data centers
  • central offices
