MAX2022
General Description
The MAX2022 low-noise, high-linearity, direct conversion
quadrature modulator/demodulator is designed for single
and multicarrier 1500MHz to 3000MHz UMTS/WCDMA,
LTE/TD-LTE, cdma2000
applications. Direct conversion architectures are advanta-
geous since they significantly reduce transmitter or receiv-
er 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 MAX2022 also yields a high level of component
integration. This device includes two matched passive mix-
ers for modulating or demodulating in-phase and quadra-
ture signals, three 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 MAX2022 operates from a single +5V supply. It is
available in a compact 36-pin TQFN package (6mm x
6mm) with an exposed paddle. Electrical performance is
guaranteed over the extended -40°C to +85°C tempera-
ture range.
