Title:
IMPEDANCE MATCHING CIRCUIT FOR COMPLEX LOAD
Document Type and Number:
WIPO Patent Application WO/2023/060549
Kind Code:
A1
Abstract:
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.
