Outdoor backhaul unit

Block diagram

Overview

Our integrated circuits and reference designs help you create outdoor units (ODUs) that enable multiband millimeter wave operation to enable >10-Gbps speeds and sub-1ms latencies. Our RF and microwave devices, mixers and modulators and power and clocking technologies allow you to complete your 5G design with confidence.

Design requirements

Outdoor backhaul units require:

  • Network synchronization over packet-based fronthaul interface.
  • High-density power management operating at high ambient temperature.
