Abstract
The invention describes a radio frequency (=RF) power amplifier (), comprising—a coupling array () comprising a plurality of nano-sized coupling elements (), wherein the coupling elements () are grouped into a number N of sub-arrays (SA-. . . SA), with each sub-array (SA-. . . SA) exhibiting•a specific resonance frequency (f. . . f) and•a specific attenuation of a mechanical self-oscillation of its coupling elements (), wherein for the coupling elements () of each sub array (SA-. . . SA), there is a stimulating means for stimulating a mechanical self-oscillation, —and a signal processing unit () for controlling the stimulating means with stimulating pulses having a pulse form and timing calculated by the signal processing unit () based on an evaluation of the spectral components of an RF signal to be amplified, namely the amplitudes (C. . . C) and phases (Φ. . . Φ) at the frequencies (f. . . f) corresponding to said specific resonance frequencies. The inventive RF power amplifier provides a high efficiency and a high linearity, in particular at high RF frequencies.
