Abstract
The invention relates to a method for automatically adjusting a single-input-port and single-output-port tunable matching circuit, for instance a single-input-port and single-output-port tunable matching circuit coupled to an antenna of a radio transceiver. The invention also relates to an automatic tuning system using this method. An automatic tuning system comprises: one user port; one target port; a sensing unit; a single-input-port and single-output-port tunable matching circuit comprising one or more adjustable impedance devices; a signal processing unit which delivers a tuning instruction as a function of one or more temperature signals and as a function of two or more real quantities depending on an impedance seen by the target port; and a tuning control unit which delivers tuning control signals, the reactance of each adjustable impedance device of the tunable matching circuit being determined by at least one of the tuning control signals.
