Most every wireless and wireline communication network, along with radar systems uses a digital modulation scheme that is susceptible to noise and jitter. Many systems still use a heterodyne architecture that converts the digital signal to a higher-frequency analog signal. This architecture relies on a mixer to create these higher frequencies. Noise from any component that reaches the mixer can be re-mixed and this reduces the sensitivity and selectivity of the entire system as re-mixed signals leak into adjacent channels. Phase noise is a big contributor to this potential issue.
