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 pre-

distorted 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 then sub-sampled at an

IF frequency of ~200 MHz which necessitates the need

for a highly linear demodulator to downmix to

quadrature IF from the Transmit frequency. By

sampling IF_I and IF_Q independently and then digitally

combining these signals, an effective doubling of the

sample rate can be achieved. Any distortion in this path

will degrade the performance of the DPD algorithm. By

utilizing an ultra-linear demodulator w/integrated DSA

such as the IDTF1320, the ACLR and/or power

consumption of the full Tx system can be improved

significantly.
