Abstract:
1. A voice data and radio frequency (RF) integrated circuit (IC) comprising: an RF transmitter, that generates an RF signal to a power amplifier module wherein the power amplifier module includes a plurality of power amplifiers and a switching network coupled to the plurality of power amplifiers, the switching network coupling a transmit signal from a selected one of the plurality of power amplifiers in response to at least one control signal; a processing module, coupled to the power amplifier module, that generates the at least one control signal 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; and a power management circuit, coupled to the processing module and the power amplifier module, that 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.
