ESCRIPTION
This document describes specifications for the
F1653NLGI I/Q Modulator implementing Zero-
Distortion

DVANTAGE
In typical multi-mode, multi-carrier basestation
transmitters the modulator has limited linearity and high
power consumption which penalizes the system ACLR
and system Power consumptions budgets in a Digital-
Pre-Distortion environment.
The IDTF1653 is designed to eliminate these penalties by
embedding Zero-Distortion
TM
technology into the device
such that very high IP3 and IP2 are achieved with
minimal current draw.
