Abstract: Some embodiments of the present disclosure relate to a feedback receiver comprising a threshold comparator configured to determine if the amplitude of a baseband signal is within a selection corridor (e.g., defined by an upper and lower threshold value). If the amplitude is within the selection corridor, a feedback receiver is configured to accumulate RF signal samples (e.g., amplitude and phase samples) over a time period. The accumulated RF signal samples, which correspond to substantially constant baseband amplitude values, are then averaged. The calculated averages are utilized for impedance measurements used tune an antenna tuner to limit impedance mismatch. By limiting RF amplitude and phase sample collection to associated baseband signals having an amplitude falling within the selection corridor, substantially equal average amplitudes and phases can be achieved over a relatively short measurement period (i.e., without the need for long measurement period).
