Abstract :
High Tc superconducting materials provide very high Q microwave resonators, which are supposed to make low phase noise oscillators. The expected phase noise has never been observed on operational oscillators. Our goal is to outperform the specifications of acoustic resonators and whispering gallery modes, with 2D resonators operated at 1 GHz: Q >; 100,000 low 1/f noise Si transistors, -150 dBc/Hz at 100 Hz from the carrier.
