Abstract
An embodiment of the present invention provides an apparatus, comprising an RF matching network connected to at least one RF input port and at least one RF output port and including one or more voltage or current controlled variable reactive elements; and wherein the RF matching network is tuned to optimize the RF matching network and wherein said tuning is limited by a predetermined number of tuning steps that are taken within a transmit burst and/or limited by the magnitude of each step taken within a transmit burst and/or limited to the steps only being allowed between bursts.
