DPD Demodulator for PA Linearization 3200 to 4400 MHz F1385 Datasheet Description This document describes the specification for the F1385 Digital Pre-Distortion Demodulator for PA linearization. This series of devices is offered in two frequency variants to cover common UTRA bands. Competitive Advantage In typical Base Station transmitters digital pre-distortion is employed to improve the transmitter performance. The signal out of the PA is sampled and the incoming TX chain I & Q data is predistorted to counteract the distortion inherent in the PA.
