Patent ID: 8280323

Claim:
A method for controlling an RF power amplifier and tuner connected between the RF power amplifier and an antenna using a fuzzy logic algorithm operating on Smith chart based calculations of the impedance match between the output of the RF power amplifier and the antenna input in a closed loop feedback circuit comprising the steps of: sensing the frequency of the RF signal applied to the RF power amplifier to monitor the amplifier performance of the RF power amplifier in a continuous monitoring step; and applying a self-correction tuning that reduces any impedance mismatch, the RF power amplifier having an input signal coupled thereto, the monitoring step including the step of monitoring the output power of the RF power amplifier and the input frequency of the RF input signal applied to the RF power amplifier and utilizing the results of the sensed output power and the input frequency for calculating tuner settings for controlling the tuner to provide a better match between the RF power amplifier and the antenna.
