IDTF1370NBGI is DPD Demodulator manufactured by Integrated Device Technology.
DPD Demodulator for PA Linearization
GENERAL DESCRIPTION
This document describes the specification for the IDTF1370 Digital Pre-Distortion Demodulator for PA linearization. This series of devices is offered in 2 variants to cover mon UTRA bands. See part number matrix below for additional detail.
PETITIVE ADVANTAGE
In typical basestation transmitters digital pre-distortion is employed to improve the Transmitter performance. The signal ing 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 sub-sampled at an IF frequency of...
