1 / 13 page General Description 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.
