Abstract:
1. A method for operating a power controller in a wireless communication device, comprising: receiving a mode select signal operable to identify one of a plurality of modes for the wireless communication device; generating a power controller output signal using an open loop polar modulation scheme, the power controller output signal operable to control power delivered to a high-band power amplifier and a low-band power amplifier, wherein the power controller output signal is determined using an amount of power currently being generated and a lookup table that has at least one value of power that corresponds to at least one level of current, wherein the lookup table stores power data corresponding to the power used by the high-band power amplifier and the low-band power amplifier; determining a band state for the wireless communication device; providing the power controller output signal to the high-band power amplifier when the band state is a high-band state and to the low-band power amplifier when the band state is a low-band state; and injecting a specified amount of current based on the mode identified by the mode select signal, into the high-band power amplifier when the band state is the high-band state and into the low-band power amplifier when the band state is the low-band state.
