An electrical component comprising:
- an amplifier comprising an output stage;
- a power-supply path for powering the output stage, the power supply path comprising a line comprising conductor track sections connected in parallel;
- a carrier substrate containing the amplifier and the line, the line being buried, at least partially, in the carrier substrate;
- and
- a low-pass filter that is in the carrier substrate and that is electrically connected to a path that receives an output of the amplifier, the low-pass filter comprising series oscillating circuits, each of the series oscillating circuits comprising a capacitor and an inductor in a shunt arm;
- wherein values of a capacitor and an inductor of a first one of the series oscillating circuits are such that a resonance frequency of the first one of the series oscillating circuits corresponds to a frequency of a first harmonic of a signal of the amplifier;
- wherein values of a capacitor and an inductor of a second one of the series oscillating circuits are such that a resonance frequency of the second one of the series oscillating circuits corresponds to a frequency of a second harmonic of the signal of the amplifier;
- and
- wherein lengths of the conductor track sections are such that the line has a lower impedance for a direct-current signal and a higher impedance for a high-frequency signal at an operating frequency of the amplifier.
