Abstract
In one embodiment an amplifier circuit is disclosed. The amplifier circuit comprises an amplifying device configured to amplify a radiofrequency signal, the amplifying device having an output dynamic range; a supply modulator configured to modulate a supply voltage supplied to the amplifying device when an output of the amplifying device is within a first region of the output dynamic range; a tuneable matching network coupled to an output of the amplifying device; and a load controller configured to control the tuneable matching network, when the output of the amplifying device is within a second region of the output dynamic range, and thereby modulate the load to which the output of the amplifying device is applied.
