Incabinet Solutions

Increasingly,  active antennas for 5G are using massive MIMO. A large number of B2B connections are required  between electronics and antenna array (up to 64 or 128 elements). As a result, pricing is becoming an increasingly critical factor.

EBC® - Efficient Board Connector

The new EBC® series from Rosenberger offers excellent electrical and mechanical properties such as axial and radial tolerance compensation. From a cost  perspective, the design has been optimized for mass production and enables multifunctional B2B and B2F applications. In addition, the EBC® has a unique self-aligning and centering function while  also meeting the shielding (EMI) and signal integrity (SI) requirements for MIMO applications.


  • Self-alignment and blind mate connection
  • Minimum board-to-board distance 12 mm
  • Axial tolerance ± 0.8mm and radial tolerance 4°
  • Operating frequency of DC to 8 GHz

P-SMP Variants

Rosenberger offers a wide range of new and cost-effective variants within the P-SMP series. This further guarantees the advantages of a stable blind mate connection and the high flexibility of the P-SMP series. It also enables economical and compact B2B and B2F solutions. Additional advantages are provided by a design that has been optimized for mass production and compatibility with the standard P-SMP interface. Depending on individual requirements data transfers and high performance can be achieved with minimal B2B distances.


  • 200 W at 2.2 GHz at 20 ° C continuous power
  • Frequency range from DC to 10 GHz
  • Minimum B2B distance 12.6 mm
  • Axial tolerance ± 1 mm (± 1.2 mm according to redesign) and radial tolerance 4 ° (± 0.9 mm)
  • Cost-effective design for selected components

Hybrid Solutions

For high frequency and power B2B connections, Rosenberger offers tailor-made and individual hybrid solutions. These reduce the overall size and complexity of the system and allow data and power to be transmitted over one connection. Depending on the application and specific requirements, Rosenberger will design individually optimized concepts in collaboration with the customer.
