Abstract:
The integrated circuit includes a power amplifier, an antenna, and a matching and filtering network including a direct current power supply stage on an output node of the power amplifier, a first section, and a second section. The direct current power supply stage and the two sections include inductor-capacitor “LC” arrangements configured to have an impedance that is matched to the output of the power amplifier in the fundamental frequency band. The LC arrangements of the direct current power supply stage and of the first section are furthermore configured to have resonant frequencies that are respectively adapted to attenuate harmonic frequency bands of the fundamental frequency band.
