An RFIC includes an RF transmitter, that generates an RF signal to a power amplifier module that operates a selected one of a plurality of power amplifiers, based one or more control signals. A processing module generates the control signals based on a selected one of a plurality of modes, wherein the plurality of modes include a first wireless mode corresponding to the use of the RFIC in accordance with a first wireless standard and a second wireless mode corresponding to the use of the RFIC in accordance with a second wireless standard. A power management circuit generates a plurality of power supply signals including at least one power supply signal for selectively powering only the selected one of the plurality of power amplifiers, in response to the at least one control signal, wherein the power management circuit is bonded to a bottom of the RFIC so as to dissipate heat to a printed circuit board.
