A Robust Search Algorithm of Optimal Driving Signals for Dual-Input High Power Amplifiers

This work proposes a robust algorithm to find the optimal driving signals of dual-input single-output Radio Frequency Power Amplifiers with minimal prior knowledge of the PA; while maintaining a safe operation by following the efficiency ridge up to the maximum output power. The proposed algorithm a...

Summary:This work proposes a robust algorithm to find the optimal driving signals of dual-input single-output Radio Frequency Power Amplifiers with minimal prior knowledge of the PA; while maintaining a safe operation by following the efficiency ridge up to the maximum output power. The proposed algorithm avoids exhaustive or guided search of all input conditions, preventing dangerous ones that may damage the devices. The proposed algorithm is validated in a 400W dual-input sequential load-modulated balanced amplifier.
