Abstract
A synthesizer includes a second frequency-synthesizing stage comprising a radiofrequency oscillator configured to oscillate at a frequency αfo when it is synchronized with a signal s0(t), where α is a rational number different from one such that αf0=ft. The radiofrequency oscillator has a magnetoresistive device within which there flows a spin-polarized electrical current to generate a signal st(t) oscillating at the frequency ft on an output electrode connected to the rendering terminal. This device is formed by a stack of magnetic and non-magnetic layers, a synchronization terminal for synchronizing the frequency of the oscillating signal st(t) with the frequency of the signal received at the synchronization terminal. The synchronization terminal being connected to the output terminal of the first stage to receive the signal s0(t).
