The architecture of a polar-modulated power amplifier module is described. The module works at any degree of an amplifier's linearity and with higher efficiency than in commonly accepted architectures.
This article describes the architecture of a power amplifier module for polar-modulated schemes. Polar-modulated power amplifiers use polar coordinates' representation of a signal-vector (vs. the traditional Cartesian I-Q representation used in the W-CDMA modulation scheme, for example). In this scheme, the recombination of coordinates is done at the output...
