Astrium Frequency Control Products group has an end-to-end capability in the area of quartz-based timing and frequency control solutions. This includes growing the highest purity quartz in the world, which results in the smallest radiation-induced frequency changes.The Frequency Control Product line ranges from simple VCXO and TCXO oscillators to Master Reference Oscillator Equipments A miniature Temperature-Compensated Crystal Oscillator for space applications. The oscillator provides a mission frequency control of less than ±3ppm plus low phase noise, low mass and low power consumption. The TCXO-B uses a 3rd overtone AT-cut resonator fabricated from Astrium’s High Purity Quartz. This oscillator achieves higher output frequencies than the standard TCXO-S product, by the use of internal frequency multiplication. Lower spurious levels are obtained at microwave frequencies if TCXO-B is used as the reference.
