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 12):
The LNA circuit of  claim 10 , further comprising:\n an output port for outputting an amplified RF output signal corresponding to the RF input signal; and a second transistor cascoded with the first transistor, wherein the second transistor comprises a second source connected to a first drain of the first transistor, and a second drain connected to the output port and to a voltage source.
