Sierra One platform for all 5G RU applications
One platform for all 5G RU applications
Sierra is a highly-integrated single-chip 4G / 5G open radio solution
One platform that powers all radio applications from small cells to massive MIMO arrays. The combined hardware and software solution provides RU designers with a flexible system building block.
Let Sierra help you design RUs with:
- High performance
- Low latency
- Low power consumption
- Short time-to-market
Sierra integrates 5 sub-systems into a single chip
providing a complete software-programmable radio signal processing engine for O-RAN radio units
- RF Transceiver supporting up to 8 transmitters
- Digital Front End (DFE) including DPD, crest factor reduction (CFR), and Passive Intermodulation (PIM) cancellation
- Low-PHY baseband processor supporting 5G, 4G, and NB-IoT air interfaces
- O-RAN Alliance Split 7.2x fronthaul interface
- 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
Sierra integrates MaxLIN™
The industry's most powerful DPD / CFR technology
