Abstract
This work presents a novel technique for reducing oscillator phase noise. A high-temperature superconducting (HTSC) limiter is implemented in a feedback oscillator in order to operate the amplifier in its linear region. Less 1/f-noise is upconverted by the amplifier which leads to reduced phase noise in the oscillator. A decrease of phase noise up to 10 dB at 1 kHz offset from the carrier could be measured. The new device is well suited for integration in an HTSC microstrip resonator layout.
