Abstract
An embodiment of the present invention provides an amplifier system, comprising at least one variable impedance matching network, the output of which provides the input to at least one amplifier stage or provides an output of the power amplifier itself, and a bias network associated with the at least one amplifier stage. The amplifier system may further comprise a controller enabling impedance control to the at least one variable impedance matching network and a supply voltage provided to the at least one variable impedance network and/or the at least one amplifier stage and wherein the at least one variable impedance network and the at least one amplifier stage may be a plurality of impedance networks connected to a plurality of amplifier stages. The at least one variable impedance network may include at least one variable capacitor and the at least one variable capacitor may be a voltage tunable dielectric capacitor which may include Parascan® voltage tunable dielectric material.
