DPD Demodulator for PA Linearization GENERAL DESCRIPTION This document describes the specification for the IDTF1320 Digital Pre-Distortion Demodulator for PA linearization. This device is one of 2 variants to cover common UTRA bands. See the Part# Matrix below for details. COMPETITIVE ADVANTAGE In typical basestation transmitters a digital pre-distortion loop is employed to improve the Transmitter performance. The signal coming out of the PA is sampled so that the I&Q data at Baseband can be predistorted before being sent to the Tx DAC to counteract the distortion inherent in the downstream PA.
