High-Linearity, 650MHz 1000MHz Upconversion/ Downconversion Mixer with Buffer/Switch
MAX2032 high-linearity passive upconverter downconverter mixer designed provide +33dBm IIP3, conversion loss 650MHz 1000MHz frequency range support multitude base-station applications. With 650MHz 1250MHz frequency range, this particular mixer ideal high-side injection architectures. pin-to-pincompatible mixer meant low-side injection, refer MAX2029. addition offering excellent linearity noise performance, MAX2032 also yields high level component integration. This device includes doublebalanced passive mixer core, dual-input selectable switch, buffer. On-chip baluns also integrated allow single-ended input downconversion output upconversion) single-ended inputs. MAX2032 requires nominal drive 0dBm, supply current guaranteed below 100mA. MAX2032 compatible with MAX2039/ MAX2041 1700MHz 2200MHz mixers, making this family passive upconverters downconverters ideal applications where common layout used both frequency bands. MAX2032 available compact 20-pin thin package (5mm 5mm) with exposed pad. Electrical performance guaranteed over extended -40°C +85°C temperature range.

Keep signal lines short possible reduce losses, radiation, inductance. best performance, route ground-pin traces directly exposed under package. exposed MUST connected ground plane PCB. suggested that multiple vias used connect this lower-level ground planes. This method provides good RF/thermal conduction path device. Solder exposed bottom device package PCB. MAX2032 evaluation used reference board layout.
