MAX19999 Datasheet | Maxim Integrated

19-4293; Rev 0; 10/08 .. Dual, Si Ge High-Linearity, 3000MHz to 4000MHz Downconversion Mixer with LO Buffer General Description The MAX19999 dual-channel downconverter provides 8.3d B of conversion gain, +24d Bm input IP3, +11.4d Bm 1d B input pression point, and a noise figure of 10.5d B for 3000MHz to 4000MHz Wi MAX™ and LTE diversity receiver applications. With an optimized LO frequency range of 2650MHz to 3700MHz, this mixer is ideal for low-side LO injection architectures. In addition to offering excellent linearity and noise performance, the MAX19999 also yields a high level of ponent integration. This device includes two double-balanced passive mixer cores, two LO buffers, and a pair of differential IF output amplifiers. Integrated onchip baluns allow for single-ended RF and LO inputs. The MAX19999 requires a nominal LO drive of 0d Bm and a typical supply current of 388m A at VCC = +5.0V or 279m A at VCC = +3.3V. The MAX19999 is pin patible with the MAX19997A 1800MHz to 2900MHz mixer and pin similar with the MAX19985/MAX19985A and MAX19995/MAX19995A series of 700MHz to 2200MHz mixers, making this entire family of downconverters ideal for applications where a mon PCB layout is used across multiple frequency bands. The MAX19999 is available in a pact 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. o o o o o o o o o o o o o o Features 3000MHz to 4000MHz RF Frequency Range 2650MHz to 3700MHz LO Frequency Range 50MHz to 500MHz IF Frequency Range 8.3d B Conversion Gain +24d Bm Input IP3 10.5d B Noise Figure +11.4d Bm Input 1d B pression Point 74d Bc Typical 2 x 2 Spurious Rejection at PRF = -10d Bm Dual Channels Ideal for Diversity Receiver Applications Integrated LO Buffer Integrated LO and RF Baluns for Single-Ended Inputs Low -3d Bm to +3d Bm LO Drive Pin patible with the MAX19997A 1800MHz to 2900MHz Mixer Pin Similar to the...
