Abstract:
An automatic impedance-matching method for a radiofrequency reception chain, which includes an antenna, an amplifier and a configurable impedance-matching network, arranged between the antenna and an input of the amplifier. The method includes two steps: acquiring measurement of a gain of the reception chain and of a noise level at an output of the amplifier and tuning the impedance-matching network according to the measurements. A radiofrequency reception chain allowing the method to be implemented is also provided.
