IDTF1320NBGI
IDTF1320NBGI is DPD Demodulator manufactured by Integrated Device Technology.
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 mon UTRA bands. See the Part# Matrix below for details.
PETITIVE ADVANTAGE
In typical basestation transmitters a digital pre-distortion loop is employed to improve the Transmitter performance. The signal ing 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. The signal coupled from the PA is adjusted via a digital step attenuator to a lower level and...
