A control method of adaptive tracking counterbalance for feedforward linear power amplifier at least inserts pilot-frequency signal into counterbalance loop in adaptive tracking counterbalance control device of feed forward linear power amplifier as it detects counterbalance result of pilot frequency in real time with adaptive tracking course to be carried on in reference to pilot frequency, when there is no signal, and it detects counterbalance result of signal in real time with the adaptive tracking course to be carried on in reference to actual signal, when there is a signal. The method has a quick speed of tracking and can finally achieve the optimum result of counterbalance between the operational signal and the intermodulation product. |
