The present invention is directed to a system for amplifying a radio frequency (RF) drive signal, the system includes a divider having one input port and N output ports. The divider is configured to split the RF drive signal into N-output signals, wherein N is an integer value. N-control elements are coupled to the divider. Each switch of the N-control elements is coupled to one of the N-output ports. N-amplifiers are coupled to the N-control elements. Each of the N-amplifiers is coupled to a corresponding one of the N-control elements, and each amplifier is turned ON in response to being driven by the corresponding one of the N-control elements. A combiner is coupled to the N-amplifiers and includes N-input ports and one output port. The N-inputs are coupled to the N-amplifiers. Each input of the N-inputs is configured to receive an RF signal propagating from a corresponding one of the N-amplifiers. The output port provides an RF output signal that is substantially equal to the sum of the RF signals propagating from the N-amplifiers.
