MAX2021
High-Dynamic-Range, Direct Up-/Downconversion
650MHz to 1200MHz Quadrature Mod/Demod
General Description
The MAX2021 low-noise, high-linearity, direct upcon-
version/downconversion quadrature modulator/demod-
ulator is designed for RFID handheld and portal
readers, as well as single and multicarrier 650MHz to
1200MHz GSM/EDGE, cdma2000 ? , WCDMA, and
iDEN ? 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 MAX2021 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 MAX2021 operates from a single +5V supply. It is
available in a compact 36-pin TQFN package (6mm x
6mm) with an exposed pad. Electrical performance is
guaranteed over the extended -40°C to +85°C temper-
ature range.
