Embodiment Construction

[0053] The general principle of the invention is based on the reuse of one (or more) input / output ports of a temperature-controlled RF resonator to propagate RF signals used by some components present inside the thermally insulated enclosure of the RF resonator (e.g. RF input signal 120e or RF output signal 120s) and LF signals (eg LF power signal 130ali or LF electrical measurement signal 140mes). In this way, heat losses are reduced, which in turn reduces the energy consumption associated with heating the enclosure.

[0054] about figure 2 , a temperature-controlled RF resonator 200 according to an embodiment of the invention is now presented.

[0055] RF resonator 200 uses the above in conjunction with figure 1 Some of the constituent elements of the RF resonator 100 are discussed. More specifically, RF resonator 200 also includes thermally insulated housing 110 within which is implemented:

Abstract

The invention relates to a temperature controlled RF resonator (200) comprising a thermally insulated housing (110) inside which the following are implemented:-at least one resonating element (120) configured to deliver an RF output signal (120s) when supplied with an RF input signal (120e); -at least one heating element (130) configured to supply thermal energy within the thermal enclosure when the at least one heating element is powered by an LF power signal (130ali); and-at least one temperature probe (140) configured to deliver an LF electrical measurement signal (140mes) as a function of a temperature inside the thermal enclosure. Such an RF resonator comprises at least one input / output port (200es1, 200es2) which passes through the thermally insulating housing and propagates at least: one of the RF signals (120e, 120s); and-a further signal of the LF electrical signals (130ali, 140mes).

Description

technical field [0001] The field of the invention is that of precision frequency sources. [0002] More specifically, the present invention relates to a temperature controlled radio frequency (or RF) resonator and corresponding RF oscillator. [0003] Thus, the present invention has many applications, both for analog applications, such as in the field where precision RF signal generation is required, and for digital applications, such as in the field where precision clock generation is required. Examples include, but are not limited to, RF communications (eg, cellular, military, space, etc.), banking transactions, etc. that require high clock precision. Background technique [0004] Both analog applications (for example, for RF carrier generation) and digital applications (for example, for clock generation intended to clock digital flip-flop circuits) require a frequency source to generate any type of periodic signal. [0005] Many RF frequency sources are based on using o...
