Summary:A power amplifier circuit, including: an input node configured to receive a radio frequency (RF) signal; an output node configured to output an amplified RF signal; a main path switchably coupled between the input node and the output node, and including a first plurality of amplification stages to generate a first amplified RF signal; a bypass path switchably coupled between the input node and the output node, and including at least one second amplification stage to generate a second amplified RF signal; and a coupling switch configured to reuse at least a portion of the bypass path to drive the main path to generate a third amplified RF signal.
