IDTF1653NLGI

ZIF/CIF Modulator GENERAL DESCRIPTION This document describes specifications for the F1653NLGI I/Q Modulator implementing ZeroDistortionTM technology for low power consumption with improved ACLR. This device interfaces directly to a high performance dual DAC. COMPETITIVE ADVANTAGE 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 DigitalPre-Distortion environment. The IDTF1653 is designed to eliminate these penalties by embedding Zero-DistortionTM technology into the device such that very high IP3 and IP2 are achieved with minimal current draw.  Power consumption 45%  IM3 Distortion 14 dB PART# MATRIX Part# RF freq Range F1650 600 – 2400 F1653 600 – 2900 IP2O +60 dBm +64 dBm Power Cons. 587 mW 587 mW IP3O Noise +36 dBm +36 dBm -158 dBm/Hz -159 dBm/Hz IDTF1653NLGI Datasheet 600MHz to 2900MHz FEATURES  Power Gain = 3dB  Direct 100Ω differential drive from Tx DAC  < 590mW Power Consumption  -159 dBm/Hz Output Noise  -161 dBc/Hz Internal LO Path Noise  IP2O = +64 dBm @ 2GHz  IP3O = +36 dBm @ 2GHz  Excellent native LO and image suppression  600 MHz input 1dB Bandwidth  600 MHz to 2900 MHz RF BW  Fast Settling for TDD (< 200 nsec)  3.3V Single Power Supply  LO port can be driven single ended or differential  4mm x 4mm, 24-pin TQFN package DEVICE BLOCK DIAGRAM 0 90 Zero-DistortionTTMM Zero-DistortionTM M...
