Baseband unit (BBU)

Block diagram


Our integrated circuits and reference designs help you create baseband units (BBUs) with signal integrity and low power while designing to 5G standards. Use the interactive system diagram below to design a system that is compatible with the latest processors/FPGAs and meets connectivity needs.

Design requirements

Modern BBU designs require:

  • Network synchronization over packet-based fronthaul interface.
  • Best-in-class signal integrity for ever-increasing data rates.
  • Highly-efficient power management for high ambient temperature environments.
