Synchronous Clock and RF Carrier Transmission for Radio Access Network Fronthaul

Systems and Control 2025-06-09 v1 Systems and Control Signal Processing

Abstract

We simultaneously achieve clock synchronisation, clock-synchronised data transmission and ultra-low noise RF carrier generation by combining clock phase caching and frequency comb transmission in radio access networks (RAN). We demonstrate <100fs jitter for 25GHz RF carrier and 2.5GHz clock, and 16-hour 6.6ps RMS wander.
