Overview
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.
The PA signal is adjusted via a digital step attenuator to a lower level and then sub-sampled at an IF frequency of ~350 MHz which necessitates...
