Empower RF Systems is proud to announce the approval of a new patent related 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.
