Latest Patents

Proctor's latest patents include advancements in adaptive digital predistortion linearization and feed-forward correction. This technology involves a digitally implemented, look-up table-based mechanism that compensates for distortion generated in RF power amplifiers. The input signal to the RF amplifier is stored for comparison with the measured RF output. In both the predistortion and feed-forward signal processing paths, the magnitude of the complex waveform of the input signal is extracted to derive a read-out address to a dual-port RAM, which stores weights to be multiplied by the input signal. In the predistortion signal processing path, the product is coupled to the RF power amplifier. In the feed-forward correction loop, the product is amplified by an auxiliary feed-forward RF amplifier and coupled into the amplified output signal path of the RF power amplifier.
