| 20100156540 | AMPLIFIER ARCHITECTURE FOR POLAR MODULATION - The present invention relates to an electronic device for power efficient linear amplification. The electronic device includes an amplifier (RF-PA) for amplifying a phase modulated signal (PM). The amplifier (RF-PA) is adapted to be controlled by a first modulating signal (AM high) for modulating the amplitude of the phase modulated signal (PM) above a predetermined amplitude value. The electronic device is further adapted to attenuate an output signal of the amplifier (RF-PA) for providing amplitude modulation below the predetermined amplitude value. | 06-24-2010 |
