IDTF653NLGI GENERAL DESCRIPTION This document describes specifications for the F653NLGI I/Q Modulator implementing Zero- Distortion TM 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 Digital- Pre-Distortion environment. The IDTF653 is designed to eliminate these penalties by embedding Zero-Distortion TM technology into the device such that very high IP3 and IP are achieved with minimal current draw. Power consumption 45% IM3 Distortion 4 db FEATURES Power Gain = 3dB Direct 00Ω differential drive from Tx DAC < 590mW Power Consumption -59 dbm/hz Output Noise -6 dbc/hz Internal LO Path Noise IP O = +64 dbm @ GHz IP3 O = +36 dbm @ GHz Excellent native LO and image suppression 600 MHz input db Bandwidth 600 MHz to 900 MHz RF BW Fast Settling for TDD (< 00 nsec) 3.3V Single Power Supply LO port can be driven single ended or differential 4mm x 4mm, 4-pin TQFN package PART# MATRIX Part# RF freq Range IP O Power Cons.

Supply noise can degrade noise figure and fast transients can trigger ESD clamps and cause them to fail. Supply voltage change or transients should have a slew rate smaller than V/0uS. In addition, all control pins should remain at 0V (+/-0.3V) while the supply voltage ramps or while it returns to zero. Zero-Distortion TM Modulator 7 RevO, April 05

The voltage set by VR has a DC path through the balun transformer T to pins BB_I+ and BB_I-, as highlighted. This also applies for VR4, T, and pins BB_Q+ and BB_Q-. With this configuration, the same voltage will be applied to BB_I+ and BB_I- and the same voltage will be applied to BB_Q+ and BB_Q-. The I and Q common mode voltages may be different from each other to null LO (carrier) leakage. Zero-Distortion TM Modulator 8 RevO, April 05
