Abstract:
An amplifier circuit for amplifying an input signal includes a transistor configured to receive the input voltage via an input port, and a second-harmonic trap connected between the transistor and ground, the second-harmonic trap having an impedance high enough to enable the second-harmonic trap to act as an open circuit at a second harmonic frequency of a voltage provided by the transistor. The second-harmonic trap includes a transformer including a primary winding connected to ground and a secondary winding, the primary winding receiving the voltage provided by the transistor. The second-harmonic trap further includes a variable capacitor connected in parallel with the secondary winding of the transformer, the variable capacitor having an adjustable capacitance that may be adjusted for the second-harmonic trap to act as the open circuit at the second harmonic frequency.

Claim (Index 21):
The amplifier circuit of  claim 8 , where the controller is further programmed to adjust the adjustable capacitance of the variable capacitor in response to feedback based on at least one of gain of the amplifier, current through the amplifier, and LC resonance of the LC resonance circuit.
