Abstract:
A power amplifier system can include a plurality of driver amplifiers and a plurality of power amplifiers, where each driver amplifier and power amplifier includes at least one respective input port and at least one respective output port. The power amplifier system also includes a shared inductive device that provides common interstage matching between the respective output ports of the plurality of driver amplifiers and the respective input ports of the plurality of power amplifiers. The shared inductive device can be a shared inductor or a shared transformer.
