The MAX9984 high-linearity downconversion mixer provides
8.1dB gain, +25dBm IIP3, and 9.3dB NF for
400MHz to 1000MHz base-station receiver applications†.
With an optimized 570MHz to 850MHz LO frequency
range, this particular mixer is ideal for low-side
LO injection receiver architectures in the cellular band.
High-side LO injection is supported by the MAX9986,
which is pin-for-pin and functionally compatible with the
MAX9984.
In addition to offering excellent linearity and noise performance,
the MAX9984 also yields a high level of component
integration. This device includes a double-balanced
passive mixer core, an IF amplifier, a dual-input LO selectable
switch, and an LO buffer. On-chip baluns are also
integrated to allow for single-ended RF and LO inputs.
The MAX9984 requires a nominal LO drive of 0dBm, and
supply current is guaranteed to be below 265mA.
The MAX9984/MAX9986 are pin compatible with the
MAX9994/MAX9996 1700MHz to 2200MHz mixers,
making this entire family of downconverters ideal for
applications where a common PC board layout is used
for both frequency bands. The MAX9984 is also functionally
compatible with the MAX9993.
The MAX9984 is available in a compact, 20-pin, thin
QFN package (5mm x 5mm) with an exposed paddle.
Electrical performance is guaranteed over the extended
-40°C to +85°C temperature range.
