The MAX2023 low-noise, high-linearity, direct upconver-

sion/downconversion quadrature modulator/demodulator

is designed for single and multicarrier 1500MHz to

2300MHz DCS 1800/PCS 1900 EDGE, cdma2000

WCDMA, and PHS/PAS base-station applications.

Direct conversion architectures are advantageous

since they significantly reduce transmitter or receiver

cost, part count, and power consumption as compared

to traditional IF-based double-conversion systems.

In addition to offering excellent linearity and noise perfor-

mance, the MAX2023 also yields a high level of compo-

nent integration. This device includes two matched

passive mixers for modulating or demodulating in-phase

and quadrature signals, two LO mixer amplifier drivers,

and an LO quadrature splitter. On-chip baluns are also

integrated to allow for single-ended RF and LO connec-

tions. As an added feature, the baseband inputs have

been matched to allow for direct interfacing to the trans-

mit DAC, thereby eliminating the need for costly I/Q

buffer amplifiers.

The MAX2023 operates from a single +5V supply. It is

available in a compact 36-pin thin QFN package (6mm

x 6mm) with an exposed paddle. Electrical perfor-

mance is guaranteed over the extended -40°C to

+85°C temperature range.
