Based on the Thiele equation for the vortex spin transfer nano-oscillator (STNO) we obtaine truncated equations for the output amplitude and phase of the oscillator. On the basis of the resistive equivalent circuit we consider operating characteristics of the STNO and find the optimal parameter values satisfying the maximum output power at the load. Based on this model it we find the tuning frequency range of STNO. These characteristics are in qualitative agreement with the experimental results.
