MAX19999
Dual, SiGe High-Linearity, 3000MHz to 4000MHz Downconversion Mixer with LO Buffer
Lowest Noise, Highest Linearity 3000MHz to 4000MHz Dual, SiGe Mixer for WiMAX and LTE Base Stations, Featuring Superior IIP3, NF, and 2RF-2LO Performance
|
Status
Active: In Production.
Description
The MAX19999 dual-channel downconverter provides 8.3dB of conversion gain, +24dBm input IP3, +11.4dBm 1dB input compression point, and a noise figure of 10.5dB for 3000MHz to 4000MHz WiMAX™ 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 component integration. This device includes two double-balanced passive mixer cores, two LO buffers, and a pair of differential IF output amplifiers. Integrated on-chip baluns allow for single-ended RF and LO inputs.
The MAX19999 requires a nominal LO drive of 0dBm and a typical supply current of 388mA at VCC = +5.0V or 279mA at VCC = +3.3V.
The MAX19999 is pin compatible 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 common PCB layout is used across multiple frequency bands.
The MAX19999 is available in a compact 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.
