Dual, SiGe High-Linearity, 3000MHz to
4000MHz Downconversion Mixer with LO Buffer
General Description
Features
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 fre-
quency range of 2650MHz to 3700MHz, this mixer is
ideal for low-side LO injection architectures.
In addition to offering excellent linearity and noise per-
formance, the MAX19999 also yields a high level of
component integration. This device includes two dou-
ble-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 V CC = +5.0V
or 279mA at V CC = +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 T C = -40°C to +85°C.
