Theoretical investigation of an ultra-low phase noise microwave oscillator based on an IF crystal resonator-amplifier and a microwave photonic frequency transposer

Resonator Q-factor and amplifier flicker noise are the most important parameters that determine the phase noise of microwave oscillators. The Q-factor of intermediate frequency (IF) crystal resonators at IF frequencies can be larger than that of microwave resonators at microwave frequencies. In ...
