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 5):
The amplifier circuit of  claim 1 , wherein the transistor is a first field effect transistor (FET) having a gate connected to the input port via an input inductor and an input capacitor for receiving the input voltage, and a source connected to the primary winding of the transformer, and\n wherein the voltage provided by the transistor and received by the primary winding is a source voltage output by the source of the first FET.
