Patent ID: 8749317

Claim:
A linear amplification with nonlinear components (LINC) modulator, comprising: a separator that generates a plurality of constant envelope signals from a source signal; a plurality of arms through which the plurality of the constant envelope signals are passed, each arm comprising; a filter that compares frequencies of components of the constant envelope signals with a threshold frequency to generate a first signal including a first frequency part of the source signal, the first frequency part being composed of frequencies lower than a predetermined frequency; a processor that generates a second signal including a second frequency part of the source signal whose frequencies are different from the first frequency part of the first signal and performs a frequency signal distortion of the second signal to generate a distorted signal, the frequency signal distortion being defined using the first signal and the second signal; and a quadrature modulator that multiplies the first signal and the distorted signal to reconstruct the constant envelope signals.
