<p>The synthesizer (10) has a first control device (30) controlling frequency of a first controlled oscillator (1) on a basis of a first reference frequency. A second controlled oscillator (3) is controlled by a second control device (31). The second control device controls frequency of the second oscillator on a basis of a second reference frequency. An integer frequency divider (5) divides a frequency of a clock signal (4) by a variable integer factor, and produces another clock signal (6) whose frequency is continuously variable by modifying the factor and by controlling the second oscillator. An independent claim is also included for a radiofrequency device including an antenna for emitting an output signal of a radiofrequency amplifier.</p> |
