A method for operating a power controller in a wireless communication device is provided that includes generating a power controller output signal using an open loop polar modulation scheme. The power controller output signal is operable to control the power delivered to a high-band power amplifier and a low-band power amplifier. A band state is determined for the wireless communication device. The power controller output signal is provided 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.
