Overview

Our integrated circuits and reference designs help you create small cell base stations that enable multiband operation, higher bandwidth and better system reliability. Our analog front-end devices use a new RF sampling architecture, while our companion power and clocking technologies allow you to complete your 5G design with confidence.

Design requirements

Small cell base stations require:

  • Highly integrated analog front-end devices with wide bandwidth and multiband operation.
  • Network synchronization over packet-based fronthaul interface.
  • High-density power management operating at high ambient temperature.
