Abstract
Device for compensating a DC component inherent in any radio frequency chain in which from a single measurement, generally obtained from a digital stage, a set of multiple compensation values is determined by a compensation value vector generating module and which compensation values are applied to multiple compensation points of the analog chain. The compensation values are calculated by an iterative process converging toward cancellation of the DC component and avoid saturating amplification components and components of the analog-to-digital converter. The module includes compensation value calculation units each configured to calculate a respective compensation value and provide the calculated compensation value to the respective compensation point.
