METHOD FOR SENSING AND CALIBRATING ANTENNA TUNER DEVICE PERFORMANCE IN CELLULAR HANDSET

摘要

Systems and methods for calibrating antenna tuner device parameters can involve measuring a first signal level of an antenna tuner device, adjusting a tuning setting of the antenna tuner device, measuring one or more adjusted signal levels of the antenna tuner device, determining a level change between the first signal level and the one or more adjusted signal levels, comparing the level change to a predefined reference level change, and adjusting a device setting of the antenna tuner device to compensate for a difference between the level change and the predefined reference level change.
