    Abstract: An embodiment of the present disclosure relates to a method of controlling a power amplifier (PA). The PA can comprise a main PA path and an auxiliary PA path. The auxiliary PA path can have a plurality of turn-on settings. The method can comprise: determining a power back off gain and a lower bound gain for the PA; and performing an iterative auxiliary PA turn-on setting selection process. The selection process can comprise: determining an instantaneous power input to the PA; based on the instantaneous power input, choosing a turn-on setting in the plurality of turn-on settings of the auxiliary PA path that causes an instantaneous gain of the PA to be between the power back off gain and the lower bound gain; and applying the chosen turn-on setting to the auxiliary PA path.

    Abstract: A dual-drive power amplifier (PA) where the PA core includes a differential pair of transistors Ml and M2 that are driven by a coupling network having two transmission-line couplers, where a first transmission line section of a coupler is configured to transmit an input signal Vin through to drive a gate of the opposite transistor, while the second transmission line section is grounded at one end and coupled with the first transmission line section such that a coupled portion aVin of the input signal Vin drives the source terminal of a corresponding transistor. The arrangement of the coupling network allows the source terminals to be driven below ground potential. Embodiments disclosed here further provide an input matching network, a driver, an inter-stage matching network, and an output network for practical implementation of the PA core.
