Abstract
In accordance with some embodiments of the present disclosure, a control path for a wireless communication device may include a radio frequency coupler having a coupled port and a terminated port, the radio frequency coupler configured to couple at least a portion of a transmission power of a transmission line coupled to the antenna tuner such that the coupled port carries a first signal indicative of an incident power transmitted to an antenna coupled to the antenna tuner and the terminated port carries a second signal indicative of a reflected power reflected by the antenna. the control path may also include a control module configured to communicate the one or more control signals to the antenna tuner for controlling the impedance of the antenna tuner based at least on the first signal and the second signal.
