Why FPGAs
Flexibility for Evolving Standards
FPGAs are inherently reprogrammable, enabling rapid adaptation to new wireless standards—whether it’s shifting functional splits, protocol updates, or fresh spectrum allocations. Stay ahead of change without redesigning your hardware.
Power and Performance Efficiency
Built on advanced nodes with Hyperflex™ architecture, Altera FPGAs deliver industry-leading performance per watt—enabling real-time signal processing, high throughput, and lower OPEX without sacrificing flexibility or upgradeability.
Custom Intelligence, Beamforming, and Differentiation
Embed AI/ML inference, advanced beamforming, proprietary signal processing, or unique algorithms directly into your design. With Altera production O-RAN IP library and AI/ML example designs, you can deliver tailored, differentiated features—and get to market faster.

AI Advanced Holdover: AI replaces costly OCXOs with TCXOs while maintaining holdover accuracy—or maintain longer holdover with your existing OCXO. Ideal for timing-critical applications in O-RAN, TSN, and industrial automation. Enables 30–50% oscillator BOM savings and substantially longer holdover times.
AI CSI Compression: AI compresses channel state information, reducing fronthaul bandwidth up to 10× while preserving accuracy. Essential for scalable RAN deployments and lower transport costs. This compression algorithm can be taken and modified for many compression use cases.
AI Digital Pre-Distortion: AI-enhanced digital pre-distortion improves power amplifier efficiency and linearity, reducing power draw and thermal load in radio systems. In systems with power amplifiers, DPD accuracy can dramatically decrease OPEX.
AI Channel Estimation: Improves channel estimation accuracy for better spectral efficiency and link reliability in wireless PHY systems. Useful for ORAN and custom 5G/6G radio stacks. Through using an optimized DSP Builder AI implementation, we dramatically reduce DSP blocks by 67% and M20k utilization by 58% while maintaining the same throughput as traditional implementations.
