Development of a mobile HTS cryogenic oscillator

High-temperature superconductors (HTS) have shown their potential for analog signal processing at microwave frequencies; they provide high Q resonators, the most critical component of an efficient low phase noise oscillator. Thus, a strategy to outperform state of art quartz oscillators could consist in integrating, in a monolithic block, a planar HTS resonator and a cryo-compatible transistor to build a 1 GHz oscillator. However, mobile systems may require reducing hardware size, weight and power consumption while meeting high performances, controlled costs and reliability needs. We discuss these questions and present our approach to validate the integration of HTS based oscillators into embedded systems.
