MAX19995A Datasheet | Maxim Integrated

19-4419; Rev 0; 1/09 .. Dual, Si Ge, High-Linearity, 1700MHz to 2200MHz Downconversion Mixer with LO Buffer/Switch General Description The MAX19995A dual-channel downconverter is designed to provide 8.7d B of conversion gain, +24.8d Bm input IP3, +13.5d Bm 1d B input pression point, and a noise figure of 9.2d B for 1700MHz to 2200MHz diversity receiver applications. With an optimized LO frequency range of 1750MHz to 2700MHz, this mixer is ideal for high-side LO injection architectures. Low-side LO injection is supported by the MAX19995, which is pin-pin and functionally patible with the MAX19995A. In addition to offering excellent linearity and noise performance, the MAX19995A also yields a high level of ponent integration. This device includes two doublebalanced passive mixer cores, two LO buffers, a dualinput LO selectable switch, and a pair of differential IF output amplifiers. Integrated on-chip baluns allow for single-ended RF and LO inputs. The MAX19995A requires a nominal LO drive of 0d Bm and a typical supply current of 350m A at VCC = 5.0V, or 242m A at VCC = 3.3V. The MAX19995/MAX19995A are pin patible with the MAX19985/MAX19985A series of 700MHz to 1000MHz mixers and pin similar to the MAX19997A/MAX19999 series of 1800MHz to 4000MHz mixers, making this entire family of downconverters ideal for applications where a mon PCB layout is used across multiple frequency bands. The MAX19995A is available in a 6mm x 6mm, 36-pin thin QFN package with an exposed pad. Electrical performance is guaranteed over the extended temperature range (TC = -40°C to +85°C).
