Optoelectronic oscillators are nonlinear, time-delayed, and self-sustained microwave photonic systems that have a plethora of applications in various disciplines related to microwave photonics. In this work, we introduce a frequency tunable optoelectronic oscillator that can generate up to millimeter-wave band with low phase noise by using stimulated Brillouin scattering. We propose a model that describes the temporal dynamics of the microwave envelope, thereby allowing us to track the dynamics of the amplitude and phase of the radiofrequency signal.
