Abstract[English]
A impedance matching circuit (100) is connected between the signal source (200) and the complex load (300) and comprises a resistive circuit (110) that is modulated by a modulation signal (Vmod) thereby modulating the resistive circuit (110) synchronously with a high frequency modulated broadband signal (VS) from the signal source (200). The modulation signal (Vmod) and the high frequency modulated broadband signal (VS) are based on a common low frequency baseband signal. Thereby, improved power transfer is possible with low signal distortion.[French]
La présente invention concerne un circuit d'adaptation d'impédance (100) qui est connecté entre la source de signal (200) et la charge complexe (300) et comprend un circuit résistif (110) qui est modulé par un signal de modulation (Vmod) modulant ainsi le circuit résistif (110) de manière synchrone avec un signal large bande modulé en fréquence (VS) à partir de la source de signal (200). Le signal de modulation (Vmod) et le signal large bande modulé haute fréquence (VS) sont basés sur un signal de bande de base basse fréquence commun. Ainsi, un transfert de puissance amélioré est possible avec une faible distorsion de signal.
