The MAX2023 low-noise, high-linearity, direct upconversion/
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 performance,
the MAX2023 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.
