Sierra integrates 5 sub-systems into a single chip

providing a complete software-programmable radio signal processing engine for O-RAN radio units

Sierra Integrates Five Sub-Systems

  1. RF Transceiver supporting up to 8 transmitters
  2. Digital Front End (DFE) including DPD, crest factor reduction (CFR), and Passive Intermodulation (PIM) cancellation
  3. Low-PHY baseband processor supporting 5G, 4G, and NB-IoT air interfaces
  4. O-RAN Alliance Split 7.2x fronthaul interface
  5. ARM® Cortex-A53 quad-core CPU Sub-System

New O-RAN Compliant Single-Chip Radio Solution

Sierra's complete system integration yields a feature rich, high-performance RU building block that reduces the need for multiple FPGAs/ASICs and simplifies new O-RAN development. 

Let Sierra help you design:

  • Macro and picocell O-RUs using just a single Sierra device and an appropriate RF front end
  • Massive MIMO O-RU by tiling an array of Sierra devices and connecting them to a central beamforming solution
