Abstract
A communication system is provided, including an antenna, a matching network coupled to the antenna, a controller configured to host an algorithm for controlling the matching network, and a look-up table coupled to the controller. The look-up table includes characterization data according to frequency bands and conditions. The controller is configured to refer to the look-up table to determine optimum impedance for a frequency band selected under a condition detected during a time interval, and adjust the matching network to provide the optimum impedance. Part or all of the sections related to the tunable matching scheme can be integrated on a chip.
