A wireless mobile communications terminal and a transceiver system thereof. The transceiver system comprises multiple cascaded power amplifiers and a transceiver connected to a final-level power amplifier. The final-level power amplifier comprises a power divider, a combiner, and at least two switch tubes. An input end of the power divider is connected to an output end of a previous-level power amplifier. An output end of the combiner is connected to an input end of the transceiver. A control end of each of the switch tubes is connected one output end of the power divider. A first end of each of the switch tube is connected to an input end of the combiner. A second end of the each of the switch tubes is connected to reference ground. The first end of each of the switch tube is connected to an output pin of a battery by means of an inductor.
