Across 5G infrastructure, emerging 6G platforms, satellite payloads, microwave backhaul, and non-terrestrial-network (NTN) systems, silicon architecture is increasingly becoming a defining system constraint. As bandwidth increases, antenna counts rise, and modulation schemes grow more complex, power density, integration efficiency, and thermal limits determine what can realistically be deployed — not simply what’s functionally achievable.

FPGAs remain highly effective during early development and amidst evolving standards. Their reconfigurability allows engineering teams to absorb specification changes and accelerate time-to-prototype.

However, once functional requirements stabilize and production volumes rise, optimization priorities shift. Power efficiency, mixed-signal integration, and long-term reliability move to the forefront. At that stage, many communications systems transition from programmable logic to application-specific integrated circuits (ASICs), because the architectural tradeoffs increasingly favor fixed-function silicon
