Patent ID: 8008982

Claim:
An apparatus, comprising: an RF matching network coupled to at least one RF input port and at least one RF output port and comprising one or more controllable variable reactive elements, wherein one of the at least one RF input port or the at least one RF output port is coupled to one of a source or a variable load impedance, wherein the variable load impedance is an antenna, and wherein the source is an RF transceiver; wherein said RF matching network is adapted to increase RF power transferred from said at least one RF input port to said at least one RF output port by varying signals supplied to said controllable variable reactive elements to increase the RF voltage at said at least one RF output port; and wherein said one or more controllable variable reactive elements are coupled to a bias driver circuit adapted to map one or more control signals that are output from a controller to a signal range that is compatible with said one or more controllable variable reactive elements in said RF matching network.
