Products and reference designs
Active antenna system mMIMO (AAS)
Overview
Our integrated circuits and reference designs help you create active antenna systems (AAS) that enable massive MIMO (mMIMO) and beamforming with 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
Modern active antenna systems mMIMO require:
- Reduced signal chain size and complexity while offering wide bandwidth and multi-frequency.
- High-density power management operating at high ambient temperature.
- Network synchronization over packet-based fronthaul interface.
