Low Power

Direct Quadrature Modulator

DescripTion

FeaTures

The LTC^®5599 is a direct conversion I/Q modulator de-

signed for low power wireless applications that enable

direct modulation of differential baseband I and Q signals

onanRFcarrier.Singleside-bandmodulationorside-band

suppressed upconversion can be achieved by applying

90° phase-shifted signals to the I and Q inputs. The I/Q

baseband input ports can be either AC or DC coupled to a

source with a common mode voltage level of about 1.4V.

The SPI interface controls the supply current, modulator

gain,andallowsoptimizationoftheLOcarrierfeedthrough

and side-band suppression, with sine wave or square

wave LO drive. A fixed LC network on the LO and RF ports

covers a continuous 90MHz to 1300MHz operation. An

on-chip thermometer can be activated to compensate for

gain-temperature variations. More accurate temperature

measurements can be made using an on-chip diode. In

addition, a continuous analog gain control (V_CTRL) pin

can be used for fast power control.
