Frequency Reference Distribution for Earth Stations

Large earth stations host communication systems that provide mission-critical, high-bandwidth services to multiple customers. Within these earth stations are many frequency-based devices with independent local oscillators that generate and convert carrier frequencies, and modulate and demodulate data. Locking these oscillators to a common, stable and low-noise frequency reference distribution system is fundamental to minimizing frequency issues and supporting higher data rates. This application note focuses on the important role and benefits of a frequency reference distribution system, design considerations, and best practices to deploy a system that meets large earth station reliability and quality-of-service requirements.
