Patent ID: 7787834

Claim:
A voice data and 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 memory module that stores at least one application as a plurality of operational instructions, the at least one application having a plurality of modes that each correspond to one of a plurality of use characteristics, wherein the plurality of modes include a first wireless mode corresponding to a first wireless standard and a second wireless mode corresponding to a second wireless standard; a processing module, coupled to the memory module and the power amplifier module, that executes the plurality of operational instructions and that determines a selected one of the plurality of modes based on current use characteristics of the at least one application, and generates the at least one control signal based on the selected one of the plurality of modes; and a bias control generator, coupled to the processing module and the power amplifier module, that generates a bias control signal in response to the at least one control signal, to control the biasing of the power amplifier module to a first bias for the first wireless mode and to a second bias for the second wireless mode, wherein the bias control generator generates a bias control signal to the selected one of the plurality of power amplifiers in response to the at least one control signal; 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 amplifier 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.
