This paper reports on an ultra-low phase-noise oscillator based on a GaN HEMT monolithic microwave integrated circuit reflection amplifier and an aluminum cavity resonator. It is experimentally investigated how the oscillator's phase noise depends on the cavity coupling factor, phase matching, and bias condition of the reflection amplifier. For the optimum(More)
