Macro remote radio unit (RRU)

Block diagram

Overview

Integrated circuits and reference designs help you create macro remote radio units (RRUs) that connect people and devices with higher bandwidth. Our modern radio frequency (RF) sampling radio or intermediate frequency (IF) sampling architectures enable direct, high-speed data conversion while our companion power and clocking products meet the latest 5G requirements.

Design requirements

Modern macro RRUs require:

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