DPD Demodulator for PA Linearization 1300MHz to 2900MHz F1375 Datasheet DESCRIPTION This document describes the preliminary specification for the F1375 Digital Pre-Distortion Demodulator for PA linearization. This series of devices is offered in two frequency variants to cover mon UTRA bands. PETITIVE ADVANTAGE In typical basestation transmitters digital pre-distortion is employed to improve the Transmitter performance. The signal out of the PA is sampled and the ining Tx chain I&Q data is pre-distorted to counteract the distortion inherent in the PA. The PA signal is adjusted via a digital step attenuator to a lower level and then subsampled at an IF frequency of ~200 MHz...
