Abstract (en)
[origin: WO2023072906A1] The invention relates to a radiofrequency digitizer (10) comprising a module (12) for dividing the power between: a first branch (14) comprising: - a device (16) for applying a variable gain, - a first analog-to-digital converter (18), - a first module (20) for applying a digital gain, and a second branch (15) comprising: - an analog combining/coupling module (24) connected, at the output, to the module for dividing the power, and to a branch (26) for analog feedback of the digital signal from said first analog-to-digital converter, comprising: - a digital-to-analog converter (28); - a module (30) for applying an analog gain; - a second module (32) for applying an analog gain; - a second analog-to-digital converter (34); - a second module (36) for applying a digital gain, each output of the first and second branch being connected to a digital combining/coupling module (38).
