ABSTRACT:
An integrated circuit (IC) includes a baseband processing module and a radio frequency (RF) section. The baseband processing module is coupled to convert outbound data or an outbound voice signal into at least one of amplitude modulation information, phase modulation information, and frequency modulation information. The RF section includes an oscillation module, a frequency divider, and power amplifier modules. The oscillation module produces an RF oscillation that it modulates based on the phase or frequency modulation information to produce a modulated RF signal. The frequency divider divides the frequency of the modulated RF signal to produce a frequency divided modulated RF signal. The first power amplifier module amplifies the modulated RF signal in accordance with the amplitude modulation information or a constant to produce a first frequency band outbound RF data or voice signal. The second power amplifier amplifies the frequency divided modulated RF data signal in accordance with the amplitude modulation information or a constant to produce a second frequency band outbound RF data or voice signal.
