600MHz to 1100MHz

High Linearity Direct

Quadrature Modulator

FEATURES

DESCRIPTION

The LT^®5558 is a direct I/Q modulator designed for high

performance wireless applications, including wireless

infrastructure. It allows direct modulation of an RF signal

using differential baseband I and Q signals. It supports

GSM, EDGE, CDMA, CDMA2000, and other systems. It

may also be conﬁgured as an image reject upconverting

mixer, by applying 90° phase-shifted signals to the I and

Qinputs. ThehighimpedanceI/Qbasebandinputsconsist

of voltage-to-current converters that in turn drive double-

balancedmixers.Theoutputsofthesemixersaresummed

and applied to an on-chip RF transformer, which converts

thedifferentialmixersignalstoa50Ωsingle-endedoutput.

The balanced I and Q baseband input ports are intended

for DC coupling from a source with a common-mode

voltage level of about 2.1V. The LO path consists of an LO

buffer with single-ended input, and precision quadrature

generators which produce the LO drive for the mixers.

The supply voltage range is 4.5V to 5.25V.
