MAX19995 Datasheet | Maxim Integrated

19-4253; Rev 0; 12/08 .. Dual, Si Ge, High-Linearity, 1700MHz to 2200MHz Downconversion Mixer with LO Buffer/Switch General Description The MAX19995 dual-channel downconverter provides up to 9d B of conversion gain, +24.8d Bm input IP3, +13.3d Bm 1d B input pression point, and a noise figure as low as 9d B for 1700MHz to 2200MHz diversity receiver applications. With an optimized LO frequency range of 1400MHz to 2000MHz, this mixer is ideal for low-side LO injection architectures. High-side LO injection is supported by the MAX19995A, which is pin-pin and functionally patible with the MAX19995. In addition to offering excellent linearity and noise performance, the MAX19995 also yields a high level of ponent integration. This device includes two double-balanced passive mixer cores, two LO buffers, a dual-input LO selectable switch, and a pair of differential IF output amplifiers. Integrated on-chip baluns allow for single-ended RF and LO inputs. The MAX19995 requires a nominal LO drive of 0d Bm and a typical supply current of 297m A at VCC = 5.0V or 212m A at VCC = 3.3V. The MAX19995/MAX19995A are pin patible with the MAX19985/MAX19985A series of 700MHz to 1000MHz mixers and pin similar with 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 MAX19995 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, from TC = -40°C to +85°C.
