Automatic Impedance Matching Method for Radiofrequency Circuit and Modular Emission or Reception Chain

An impedance matching method, for a transmitting or receiving system, comprising the following steps:

• connecting, in a detachable manner, a first module containing an amplifier to a second module containing impedance matching computation means;
• connecting, in a detachable manner, a third module to the second module, whilst the second module is connected to the first one, the third module containing an antenna, a matching impedances network and memory means for storing control data of the impedances network, carrying out a matching computation in the second module whilst it is thus connected in a detachable manner between the first and third modules, and providing, by the second module to the third module, control data for the matching impedances network, resulting from this computation,
• storing the control data in the memory means of the third module, and
• removing the second module and connecting, in a detachable manner, the third module to the first module in such a way as to connect the amplifier to the antenna through the matching impedances network, the latter being controlled by the stored control data.
