I would like to check if there is a way to enhance an RF equipment's phase noise figure. The considered RF acquisition homodyne system includes a mixer for carrier demodulation, amplifier and filter in the front end and offers a possible external reference clock plugging feature. Here is a diagram that describes the system's front end architecture:

enter image description here

Knowing that the system's phase noise performance is mainly defined by the used oscillator ,is there another system component that contribues to the phase noise (RF Front end amplificators or ADC for example ) ? If the acquisition is performed using an external clock reference with better phase noise,will the system's performance in terms of phase noise be equal the clock's or a possible degradation may be expected?
