System for generating at least one radio frequency signal phase-locked to a reference signal, corresponding radio frequency transmitter and receiver

A system for generating at least one radio frequency signal phase-locked to a reference signal, wherein the system comprises:

• a rotary travelling wave oscillator comprising at least one conductive ring and a plurality of sustaining amplifying cells electrically connected to said at least one ring, a radio frequency length of the ring loaded by an impedance of the amplifying cells corresponding to a frequency of said at least one radio frequency signal;
• a programmable multiplexer device designed to electrically connect an input port of the system to at least one amplifying cell that can be selected from the cells of the plurality,
• the system being designed so that the oscillator generates an oscillation signal phase-locked to the reference signal when the reference signal is injected at the input port of the system, a phase difference between the oscillation signal and the reference signal being a function of said at least one amplifying cell to which the input port is electrically connected via the programming of the multiplexer device, said at least one radio frequency signal corresponding to the oscillation signal picked up at a respective given point of said at least one ring.
