DescriptionThe MAX2022 low-noise, high-linearity, direct upconversion quadrature modulator is designed for single and multicarrier 1800MHz to 2200MHz UMTS/WCDMA, cdma2000®, and DCS/PCS base-station applications. Direct upconversion architectures are advantageous since they significantly reduce transmitter cost, part count, and power consumption as compared to traditional IF-based double upconversion systems.
In addition to offering excellent linearity and noise performance, the MAX2022 also yields a high level of component integration. This device includes two matched passive mixers for modulating in-phase and quadrature 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 thin QFN package (6mmx 6mm) with an exposed paddle. Electrical performance is guaranteed over the extended -40°C to+85°C temperature range.
