General Description
The MAX2021 low-noise, high-linearity, direct upconversion/downconversion
quadrature modulator/demodulator 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 performance, the MAX2021
also yields a high level of component 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
connections. As an added feature, the baseband inputs have been matched to
allow for direct interfacing to the transmit 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.
