MAX19993 Datasheet | Maxim Integrated

.. 19-5307; Rev 0; 6/10 Dual, Si Ge, High-Linearity, 1200MHz to 1700MHz Downconversion Mixer with LO Buffer/Switch General Description The MAX19993 dual-channel downconverter is designed to provide 6.4d B of conversion gain, +27d Bm input IP3, 15.4d Bm 1d B input pression point, and a noise figure of 9.8d B for 1200MHz to 1700MHz diversity receiver applications. With an optimized LO frequency range of 1000MHz to 1560MHz, this mixer is ideal for low-side LO injection architectures. High-side LO injection is supported by the MAX19993A, which is pinpin and functionally patible with the MAX19993. In addition to offering excellent linearity and noise performance, the MAX19993 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 device requires a nominal LO drive of 0d Bm and a typical supply current of 337m A at VCC = +5.0V or 275m A at VCC = +3.3V. The MAX19993 is pin patible with the MAX9985/ MAX19985A/MAX9995/MAX19993A/MAX19994/ MAX19994A/MAX19995/MAX19995A series of 700MHz to 2200MHz mixers and pin similar to the MAX19997A/ MAX19999 series of 1850MHz to 4000MHz mixers, making this entire family of downconverters ideal for applications where a mon PCB layout is used across multiple frequency bands. The device is available in a 6mm x 6mm, 36-pin TQFN package with an exposed pad. Electrical performance is guaranteed over the extended temperature range, from TC = -40NC to +85NC.
