Abstract:
The integrated circuit includes a power amplifier intended to provide a signal in a fundamental frequency band, an antenna, and a matching and filtering network having a first section, a second section, and a third section. The three sections include LC arrangements configured to have an impedance matched to the power amplifier's output in the fundamental frequency band. The LC arrangements of the first section and the second section are configured to have resonant frequencies adapted to attenuate the harmonic frequency bands of the fundamental frequency band.
