Temperature-controlled radio-frequency resonator and corresponding radio-frequency oscillator

A radio frequency (RF) oscillator comprising:

• a temperature-controlled RF resonator comprising:
• an insulating thermal enclosure within which are implemented:
• at least one resonant element configured to provide an RF output signal when fed with an RF input signal, said RF output signal corresponding to said RF input signal filtered around a resonant frequency of said at least one resonant element;
• at least one heating element configured to supply thermal energy within the thermal enclosure when said at least one heating element is powered by a low frequency (LF) electric power signal;
• and
• at least one temperature sensor configured to deliver an LF electric measurement signal as a function of the temperature inside the thermal enclosure;
• and
• at least one input/output port crossing said insulating thermal enclosure, said at least one input/output port propagating at least:
• one signal from among said RF input and output signals;
• and
• another signal from among said LF electric power and measurement signals,
• wherein said insulating thermal enclosure comprises an RF path on which said RF input and output signals propagate and on which said at least one resonant element is implemented, said RF path comprising a decoupling element blocking LF electric components of the LF electric power and measurement signals.
