description A method for harmonic trapping in a matching network of a power amplifier includes determining primary inductance and secondary inductance of a differential transformer of the matching network, based on a signal operating frequency of the power amplifier. An inductance value for an L-C filter is determined based on the secondary inductance and a harmonic frequency of a local oscillator (LO) signal. A capacitance value for the L-C filter is determined based on the inductance value and the harmonic frequency of the LO signal. The L-C filter is provided on an electric connection between a direct current (DC) bias voltage source and a secondary inductor of the differential transformer. The L-C filter is configured with the determined inductance value and the determined capacitance value.
