Abstract
An automatic impedance matching method for a radio-frequency chain comprises: an impedance matching network having an input and an output, a first radio-frequency device connected to the input and a second radio-frequency device connected to the output, the impedance matching network exhibiting a reconfigurable topology and comprising a plurality of reactive elements, at least one of which exhibits a variable reactance, the method comprising the choice of the configuration of the impedance matching network allowing the implementation of impedance matching while minimizing losses. An automatic impedance matching module for implementing the method is provided. Radio-frequency transmission and reception chains comprising a module are also provided.
