APPARATUS, SYSTEM, AND METHOD FOR DIGITAL MODULATION OF POWER AMPLIFIER IN POLAR TRANSMITTER

摘要

An amplifier receives an amplitude signal of a polar modulated signal at a base or gate terminal of a transistor and receives a phase modulated carrier signal of the polar modulated signal at the base or gate terminal of the transistor. The amplifier combines the amplitude signal and the phase modulated signal to produce a full complex waveform at a collector or drain terminal of the transistor.
