Abstract
As relates to the automatic impedance matching of a radiofrequency system, a system comprises three modules. In a matching phase a matching computation module is connected in a detachable manner between an amplification module and an antenna module containing an antenna, a matching impedances network, and memory means for storing control data of the network; then a matching computation is carried out; the computation module supplies control data of the network to the memory device. In a phase of using the system, the second module is removed and the antenna module is connected in a detachable manner directly to the amplification module, the matching network being controlled by the stored control data, which correspond to the desired impedance matching.
