Interfacing RF I/Q Modulators with
Popular D/A Converters

Introduction
Linear TechnologyвЂ™s High Frequency Product lineup
includes a variety of RF I/Q modulators. The purpose of
this application note is to illustrate the circuits required
to interface these modulators with several popular D/A
converters. Such circuits typically are required to maximize
the voltage transfer from the DAC to the baseband inputs
of the modulator, as well as provide some reconstruction
п¬Ѓltering. 0.52V. If the common mode DC voltage applied to the
modulatorвЂ™s baseband input terminals deviates from
this value by more than about 75mV, the device may
not meet the speciп¬Ѓcations listed in the data sheet,
because source voltage affects the current consumed
by the mixer core. The common mode voltage is approximately constant over temperature. High impedance, lower common mode DC voltage
(LT5571, LT5572) The baseband (I,Q) interface for the modulators falls into
one of three categories: The baseband input circuit of these modulators presents
a very high differential impedance (about 90k). The
I, Q inputs do not generate an internal DC voltage, but …
