Zero-DistortionTM
GENERAL DESCRIPTION
This document describes specifications for the
F1650NLGI Zero/Complex IF Modulator implementing
Zero-DistortionTM technology for low power consumption
with improved ACLR. This device interfaces directly to a
high performance Tx 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 IDTF1650 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.

— EP
Exposed Pad. Internally connected to GND. Solder this exposed
pad to a PCB pad that uses multiple ground vias to provide heat
transfer out of the device into the PCB ground planes. These
multiple via grounds are also required to achieve the specified
RF performance.

POWER SUPPLIES
All supply pins should be bypassed with external capacitors to minimize noise and fast transients. 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 1V/20uS. In addition, all control pins should remain at 0V (+/-0.3V)
while the supply voltage ramps or while it returns to zero.

APPLYING VCM AT THE BASEBAND INPUTS
With L1, L2, L3, and L4 unpopulated, the
common mode voltage is set by VR2 and VR4.
The voltage set by VR2 has a DC path through
the balun transformer T1 to pins BB_I+ and
BB_I-, as highlighted. This also applies for VR4,
T2, 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.
