New communication services and the use of complex waveforms have created a demand for highly linearized power amplifiers. Deviations from linearity show up as spectral distortions and/or modulation quality degradation (EVM) in the output of these amplifiers-that is, undesired energy, not contained in the original signal, inside or outside the frequency band of interest. Linearization techniques seek to reduce these distortions, allowing an amplifier to operate at its best spectral and power efficiency for the specific application.
This patent relates to a real time pre-distortion design and technique that is essential for broadband frequency hopping, which is especially critical for military radio communication. The main advantage of the new linearization approach is that pre-correction is being synchronized with the amplifier's distortion components in frequency, time and temperature.

The patent was submitted and authored for Empower by Paulo Correa and Andre A. Castro. In the approved abstract released by the U.S. Patent & Trademark Office the patent is described as "A system including a power amplifier and a pre-distortion module coupled to the power amplifier. The pre-distortion module includes one or more smaller versions of the power amplifier to generate a pre-distortion signal that compensates for any memory-effect or inertia present in the power amplifier with application on frequency hopping and larger (up to 1 octave) instantaneous bandwidth communication systems.
