The invention relates to a method for providing an amplified RF signal, with the steps of analysing the spectral components, namely the amplitudes and the phases at different frequencies (f 1 ...f N ), of an RF signal to be amplified or a baseband signal to be up-converted to RF and amplified subsequently, applying a supply voltage to a coupling array (11) comprising a plurality of nano-sized coupling elements (8),wherein the coupling elements (8) are grouped into a number N of sub-arrays (SA 1 ...SA N ), with each sub-array (SA 1 ...SA N ) exhibiting a specific resonance frequency (f 1 ...f N ), and a specific attenuation of a mechanical self oscillation of its coupling elements (8), stimulating mechanical self-oscillations of the coupling elements (8) of the sub-arrays (SA 1 ... SA N ) in dependence of the spectral components of the signal to be amplified, wherein during and/or prior to the amplification, the resonance frequencies (f 1 ,..., f N ) of the coupling elements (8) of the sub-arrays (SA 1 , ..., SA N ) are tuned to match the frequency components (f 1 ...f N ) of the signal to be amplified. The method enables an RF power amplifier to meet the required signal frequency distribution and to compensate for temperature drift and aging of the coupling elements.
