| 摘要 |
<p>The invention relates to a radio frequency, RF, signal generator (100), for providing an RF signal (RF_out), said RF signal generator (100) comprising:
- at least two coupling elements (2; 41; 51), wherein each coupling element (2; 41; 51) comprises two coupling electrodes (3a, 3b) at least one of which is capable of performing a mechanical self-oscillation with a specific resonance frequency (fl, .., fN) and/or a specific attenuation to enable an electric coupling between said coupling electrodes (3a, 3b) which depends on said specific resonance frequency (fl, .., fN) and/or specific attenuation,
- stimulating means (IG1, IG2, .., IGN) that are configured to selectively stimulate a mechanical self-oscillation of at least one of said coupling elements (2; 41; 51), and
- signal processing means (22) configured to determine at least one parameter characterizing an actual resonance frequency and/or an actual attenuation exhibited by at least one coupling element (2; 41; 51) in response to a stimulation applied by said stimulating means (IG1, IG2, .., IGN).</p> |
