A cryogenic low phase noise amplifier and an high Q superconductor resonator at 1 GHz have been designed and realized. A good agreement between the measured and simulated data at 80 K for these two devices is observed. An all cryogenic oscillator has also been designed with the same devices on an alumina substrate. This oscillator is still under test.
