Abstract:
An amplifier circuit includes an input port, an output port, and a reference potential port, an RF amplifier device having an input terminal electrically coupled to the input port, an output terminal electrically coupled to the output port, and a reference potential terminal electrically coupled to the reference potential port. An impedance matching network is electrically connected to the output terminal, the reference potential port, and the output port. The impedance matching network includes a reactive efficiency optimization circuit that forms a parallel resonant circuit with a characteristic output impedance of the peaking amplifier at a center frequency of the fundamental frequency range. The impedance matching network includes a reactive frequency selective circuit that negates a phase shift of the RF signal in phase at the center frequency and exhibits a linear transfer characteristic in a baseband frequency range.

Claim (Index 5):
The amplifier circuit of  claim 1 , wherein parameter values of the reactive frequency selective circuit are selected to shift a non-linear transfer characteristic region of the impedance matching network into a frequency region that is between the baseband frequency range and the fundamental frequency range.
