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 19):
The method of  claim 15 , wherein adjusting the adjustable capacitance of the variable capacitor comprises:\n determining the LC resonant frequency of the adjustable capacitance and the secondary inductance as the determined at least one parameter; determining the second harmonic frequency of the output voltage; comparing the determined LC resonant frequency to the second harmonic frequency of the output voltage; and adjusting the adjustable capacitance of the variable capacitor until the determined LC resonant frequency of the adjustable capacitance and the secondary inductance matches the reciprocal of the determined second harmonic frequency of the second harmonic of the output voltage.
